In CentOS 6 default httpd configuration, the `LoadModule ssl_module ...` is handled in `conf.d/ssl.conf`. As the `VirtualHost` configuration files in `conf.d/` are loaded in alphabetical order, this means that all files that have `<IfModule mod_ssl.c>` and are loaded before `ssl.conf` are effectively ignored. This PR moves the `LoadModule ssl_module` to the main `httpd.conf` while leaving a conditional `LoadModule` directive in `ssl.conf`.
Features
- Reads the module configuration from `ssl.conf` in case some modifications to paths have been made by the user.
- Falls back to default paths if the directive doesn't exist.
- Moves the `LoadModule` directive in `ssl.conf` inside `<IfModule !mod_ssl.c>` to avoid printing warning messages of duplicate module loads.
- Adds `LoadModule ssl_module` inside of `<IfModule !mod_ssl.c>` to the top of the main `httpd.conf`.
- Ensures that these modifications are not made multiple times.

Attempts to configure all of the following VirtualHosts for answering the HTTP challenge:
* VirtualHosts that have the requested domain name in either `ServerName` or `ServerAlias` directive.
* VirtualHosts that have a wildcard name that would match the requested domain name.
This also applies to HTTPS VirtualHosts, making Apache plugin able to handle cases where HTTP redirection takes place in reverse proxy or similar, before reaching the Apache HTTPD.
Even though also HTTPS VirtualHosts are selected, Apache plugin tries to ensure that at least one of the selected VirtualHosts listens to HTTP-01 port (configured with `--http-01-port` CLI option). So in a case where only HTTPS VirtualHosts exist, but user wants to configure those, `--http-01-port` parameter needs to be set for the port configured to the HTTPS VirtualHost(s).
Fixes: #6730
* Select all matching VirtualHosts for HTTP-01 challenges instead of just one
* Finalize PR and add tests
* Changelog entry
This will immediately address the breakage reported in #6682 and tracked at #6685. Pip 19.0.0 and 19.0.1 don't allow commas in filenames, so don't use commas in filenames in certbot-apache test code.
I've confirmed that this fixes the issue on a machine that fails with the version of certbot-auto currently in master: recent version of virtualenv, python 2.7.
Steps to test:
push master to test box
run tools/venv.py
activate venv
pip --version: 19.0.1
pip install ./certbot-apache/: fails
push branch code to test box
confirm pip --version still 19.0.1
pip install ./certbot-apache/: success

Class inheritance based approach to distro specific overrides.
How it works:
The certbot-apache plugin entrypoint has been changed to entrypoint.ENTRYPOINT which is a variable containing appropriate override class for system, if available.
Override classes register themselves using decorator override.register() which takes a list of distribution fingerprints (ID & LIKE variables in /etc/os-release, or platform.linux_distribution() as a fallback). These end up as keys in dict override.OVERRIDE_CLASSES and values for the keys are references to the class that called the decorator, hence allowing self-registration of override classes when they are imported. The only file importing these override classes is entrypoint.py, so adding new override classes would need only one import in addition to the actual override class file.
Generic changes:
Parser initialization has been moved to separate class method, allowing easy override where needed.
Cleaned up configurator.py a bit, and moved some helper functions to newly created apache_util.py
Split Debian specific code from configurator.py to debian_override.py
Changed define_cmd to apache_cmd because the parameters are for every distribution supporting this behavior, and we're able to use the value to build the additional configuration dump commands.
Moved add_parser_mod() from configurator to parser add_mod()
Added two new configuration dump parsing methods to update_runtime_variables() in parser: update_includes() and update_modules().
Changed init_modules() in parser to accommodate the changes above. (ie. don't throw existing self.modules out).
Moved OS based constants to their respective override classes.
Refactored configurator class discovery in tests to help easier test case creation using distribution based override configurator class.
tests.util.get_apache_configurator() now takes keyword argument os_info which is string of the desired mock OS fingerprint response that's used for picking the right override class.
This PR includes two major generic additions that should vastly improve our parsing accuracy and quality:
Includes are parsed from config dump from httpd binary. This is mandatory for some distributions (Like OpenSUSE) to get visibility over the whole configuration tree because of Include statements passed on in command line, and not via root httpd.conf file.
Modules are parsed from config dump from httpd binary. This lets us jump into correct IfModule directives if for some reason we have missed the module availability (because of one being included on command line or such).
Distribution specific changes
Because of the generic changes, there are two distributions (or distribution families) that do not provide such functionality, so it had to be overridden in their respective override files. These distributions are:
CentOS, because it deliberately limits httpd binary stdout using SELinux as a feature. We are doing opportunistic config dumps here however, in case SELinux enforcing is off.
Gentoo, because it does not provide a way to invoke httpd with command line parsed from its specific configuration file. Gentoo relies heavily on Define statements that are passed over from APACHE2_OPTS variable /etc/conf.d/apache2 file and most of the configuration in root Apache configuration are dependent on these values.
Debian
Moved the Debian specific parts from configurator.py to Debian specific override.
CentOS
Parsing of /etc/sysconfig/httpd file for additional Define statements. This could hold other parameters too, but parsing everything off it would require a full Apache lexer. For CLI parameters, I think Defines are the most common ones. This is done in addition of opportunistic parsing of httpd binary config dump.
Added CentOS default Apache configuration tree for realistic test cases.
Gentoo
Parsing Defines from /etc/conf.d/apache2 variable APACHE2_OPTS, which holds additional Define statements to enable certain functionalities, enabling parts of the configuration in the Apache2 DOM. This is done instead of trying to parse httpd binary configuration dumps.
Added default Apache configuration from Gentoo to testdata, including /etc/conf.d/apache2 file for realistic test cases.

This changes the apache plugin behaviour to only parse enabled configuration files and respecting the --apache-vhost-root CLI parameter for new SSL vhost creation. If --apache-vhost-root isn't defined, or doesn't exist, the SSL vhost will be created to originating non-SSL vhost directory.
This PR also implements actual check for vhost enabled state, and makes sure parser.parse_file() does not discard changes in Augeas DOM, by doing an autosave.
Also handles enabling the new SSL vhost, if it's on a path that's not parsed by Apache.
