D6082: phabricator: add a `--branch` flag to `hg phabsend`

[pulkit (Pulkit Goyal)]

Herald added a subscriber: mercurial-devel.
Herald added a reviewer: hg-reviewers.

REVISION SUMMARY
  One of the existing problems with using phabricator for us is that there is no
  way to specify that the revision/patch/differential is intended for stable
  branch.
  
  This patch adds a new flag `--branch` to `hg phabsend` command. If the
  `--branch` is passed, `hg phabsend` will add a comment to the related
  differential saying that `The review is intended for a <branch-name> branch`.
  
  I looked into other API's which we can use or other properties which can be used
  to put the branch info and didn't found anything quite useful.
  
  Future improvement can be checking the branch of the patch and commenting that
  branch name.
  
  I am not sure how to add tests for this. I tested this patch while sending this
  patch.

+    When working with multiple named branches, one can specify which branch your

+    related differential saying "This review is intented for stable branch".
