Use requests lib in HTTPClient
This change proposes switch to requests lib instead using HTTPConnection and VerifiedHTTPSConnection, requests lib is recommended for higher-level http client interface. Also HTTPConnection can't work with API server behind proxy. Change-Id: I0393aaf38e59bdfdefb0e00aaa514a3246bf639b Closes-Bug: 1500929
