phase: when phase cannot be reduced, hint at --force and return 1 (BC)

Before, trying to change the phase of a "public" node to "draft" would result
in:

  $ hg phase --draft .
  no phases changed
  [0]

With this patch:

  $ hg phase --draft .
  cannot move 1 changesets to a more permissive phase, use --force
  no phases changed
  [1]

On partial failures, the exit status is now 1 instead of 0 and the number of
changed nodes is displayed while it was only with --verbose. It seems useful to
tell the user that despite the apparent failure, something changed.

  $ hg phase --draft '5 or 7'
  cannot move 1 changesets to a more permissive phase, use --force
  phase changed for 1 changesets
  [1]
