phabricator: add a config to use curl for communication
Not sure why, but I got `phabsend` hang on work network pretty frequently.
The traceback indicates it hangs at `_sslobj.do_handshake()`:
File "mercurial/sslutil.py", line 404, in wrapsocket
sslsocket = sslcontext.wrap_socket(sock, server_hostname=serverhostname)
File "/usr/lib/python2.7/ssl.py", line 363, in wrap_socket
_context=self)
File "/usr/lib/python2.7/ssl.py", line 611, in __init__
self.do_handshake()
File "/usr/lib/python2.7/ssl.py", line 840, in do_handshake
self._sslobj.do_handshake()
I had tried adding `timeout` in various places but they seem not effective.
It seems easier to just allow shelling out to `curl` with retry and timeout
flags.
This could also be helpful for people with an older Python installed without
modern security (SNI).
