by pmaier@sysmocom.deHTTP_Adapter: allow API users to specifiy custom header
At the moment HTTP_Adapter can only make requests with a fixed
pre-defined HTTP header. However, some application may require
additional custom header lines or different values than the ones
specified in the pre-defined HTTP header.
