optionally allow redirects on HTTPClient & OTA updates (#5009)

Browse Source 
* optionally allow redirects on http OTA updates

* Refactored HTTPClient::begin(url...) & setURL functions, now only beginInternal parses URL, sets ports
Added HTTPRedirect example.

* fix indentation for style check

* add space after while for style check

* don't use deprecated begin method in redirect example

* moved redirect handling code to HTTPClient.
only GET and HEAD requests are currently handled automatically
Redirects that fail to be automatically handled return the redirect code as before

* added support for POST/303 redirect
added device redirect tests

* add missing getLocation() implementation

* if the new location is only a path then only update the URI
