phabricator: add phabsend command to send a stack
The `phabsend` command is intended to provide `hg email`-like experience -
sending a stack, setup dependency information and do not amend existing
changesets.
It uses differential.createrawdiff and differential.revision.edit Conduit
API to create or update a Differential Revision.
Local tags like `D123` are written indicating certain changesets were sent
to Phabricator. The `phabsend` command will use obsstore and tags
information to decide whether to update or create Differential Revisions.
