phabricator: introduce a `phabricator.retry` option
For the past 2 days, my connection to phab.mercurial-scm.org became extremely
poor. In practice this mean that any conduit call has a fairly high change to
hang and die. Giving the amount of call done by the phabricator extension, it
means the when I am lucky I can get 1 or 2 Diff to update after a few try, but
anything sizeable doesn't have any hope to get through.
This changesets introduce a new option for the fabricator extension to try retry
failed command itself. So that I can get Diff through.
As you can guess, this changeset managed to reach Phabricator thanks to itself.
