phabricator: add a contrib script

The default Phabricator client arcanist is not friendly to send a stack of
changesets. It works better when a feature branch is reviewed as a single
review unit. However, we want multiple revisions per feature branch.

To be able to have an `hg email`-like UX to send and receive a stack of
commits easily, it seems we have to re-invent things. This patch adds
`phabricator.py` speaking Conduit API [1] in `contrib` as the first step.
This may also be an option for people who don't want to run PHP.

Config could be done in `hgrc` (instead of `arcrc` or `arcconfig`):

    [phabricator]
    # API token. Get it from https://phab.mercurial-scm.org/conduit/login/
    token = cli-xxxxxxxxxxxxxxxxxxxxxxxxxxxx
    url = https://phab.mercurial-scm.org/
    # callsign is used by the next patch
    callsign = HG

This patch only adds a single command: `debugcallconduit` to keep the patch
size small. To test it, having the above config, and run:

    $ hg debugcallconduit diffusion.repository.search <<EOF
    > {"constraints": {"callsigns": ["HG"]}}
    > EOF

The result will be printed in prettified JSON format.

[1]: Conduit APIs are listed at https://phab.mercurial-scm.org/conduit/
