Better follow redirection for HTTPClient (#7157)

Browse Source 
* Add way to force follow redirections in `HTTPClient`

* Follow other client implementations about `HTTP_CODE_FOUND`; Small rewrite of `sendRequest` function of `HTTPClient`

* Better names for follow redirection modes in `HTTPClient`

Also changed a bit order of the enums (0 element to be DISABLED)

* Rewrite `sendRequest` to remove recursion

Also got rid of unnecessary `redirectCount` field. Now redirect counting and limiting is handled in `sendRequest` directly.

* Use new `setFollowRedirects` of `HTTPClient` instead deprecated one.

* More explanatory comment for `followRedirects_t` in HTTPClient
