MEDIUM: httpclient: allow address and port change for resolving

Browse Source 
To allow the http-request set-dst to work for the httpclient DNS
resolving, some changes need to be done:

- The destination address need to be set in the frontend (s->csf->dst)
  instead of the backend (s->csb->dst) to be able to use
  tcp_action_req_set_dst()

- SRV_F_MAPPORTS need to be set on the proxy in order to allow the port
  change in alloc_dst_address()
