`HTTPClient` does not follow POST requests (feature request)

[AgainPsychoX]

Feature request: HTTPClient stands for using HTTP 1.1 so it should allow to follow POST requests.

More information:
https://softwareengineering.stackexchange.com/questions/99894/why-doesnt-http-have-post-redirect

The RFC document mentioned in code require client confirmation to follow request with method other than GET and HEAD, so I propose additional flag to force follow the redirection (or extension to existing one, by enum?).

I will try to implement it tonight myself.

Please add [fixed-by-pr] by #7157 ?
