Add support for removing the Content-Type header to the S3 engine. This
is required for compatibility with some S3 providers.
This also adds a provider option to the S3 engine which will turn on
relevant compatibility options for specific providers.
This was required for getting MariaDB S3 engine to work with "Huawei
Cloud S3".
To get Huawei S3 storage to work on has set one of the following
S3 options:
s3_provider=Huawei
s3_ssl_no_verify=1
Author: Andrew Hutchings <andrew@mariadb.org>
Move the S3 test case variables to suite.pm to use environment variables.
Use minio credentials if a TCP connection to localhost:9000 is accepted
so the current build works corrected.

This failure was caused because of several bugs:
- Someone had removed s3-slave-ignore-updates=1 from slave.cnf, which
caused the slave to remove files that the master was working on.
- Bug in ha_partition::change_partitions() that didn't reset m_new_file
in case of errors. This caused crashes in ha_maria::extra() as the
maria handler was called on files that was already closed.
- In ma_pagecache there was a bug that when one got a read error one a
big block (s3 block), it left the flag PCBLOCK_BIG_READ on for the page
which cased an assert when the page where flushed.
- Flush all cached tables in case of ignored ALTER TABLE
Note that when merging code from 10.3, that fixes the partition bug, use
the code from this patch instead.
Changes to ma_pagecache.cc written or reviewed by Sanja
* use the environment variable HA_S3_SO, not a literal ha_s3 in cnf files
* make ConfigFactory to support empty option values
* update no_s3.result after MDEV-11412
MDEV-22088 S3 partitioning support
All ALTER PARTITION commands should now work on S3 tables except
REBUILD PARTITION
TRUNCATE PARTITION
REORGANIZE PARTITION
In addition, PARTIONED S3 TABLES can also be replicated.
This is achived by storing the partition tables .frm and .par file on S3
for partitioned shared (S3) tables.
The discovery methods are enchanced by allowing engines that supports
discovery to also support of the partitioned tables .frm and .par file
Things in more detail
- The .frm and .par files of partitioned tables are stored in S3 and kept
in sync.
- Added hton callback create_partitioning_metadata to inform handler
that metadata for a partitoned file has changed
- Added back handler::discover_check_version() to be able to check if
a table's or a part table's definition has changed.
- Added handler::check_if_updates_are_ignored(). Needed for partitioning.
- Renamed rebind() -> rebind_psi(), as it was before.
- Changed CHF_xxx hadnler flags to an enum
- Changed some checks from using table->file->ht to use
table->file->partition_ht() to get discovery to work with partitioning.
- If TABLE_SHARE::init_from_binary_frm_image() fails, ensure that we
don't leave any .frm or .par files around.
- Fixed that writefrm() doesn't leave unusable .frm files around
- Appended extension to path for writefrm() to be able to reuse to function
for creating .par files.
- Added DBUG_PUSH("") to a a few functions that caused a lot of not
critical tracing.
