push: make pushkey part advisory

The current behavior (with bundle1) is to let the rest of the push succeed if
the pushkey call (phases, bookmarks) failed (this comes from the fact that each
item is sent in its own command).

We kept this behavior with bundle2, which is highly debatable, but let us keep
thing as they are now as a start. We are about to enforce 'mandatory' pushkey
part as 'mandatory' successful, so we need to marks parts as advisory to
preserve the current (debatable) behavior.

Branch shadowing:

  $ hg branch -f default

  $ hg ci -m "clear branch name"

There should be only one default branch head

Merging and branches

  $ hg co foo

 set existing branch name fails unless force - setting existing parent branch works without force:

  $ hg branch bar
  abort: a branch of the same name already exists
  (use 'hg update' to switch to it)
  [255]

  $ hg branch -f bar
  marked working directory as branch bar

  $ hg branch foo
  marked working directory as branch foo

  $ echo bleah > a
  $ hg ci -m "modify a branch"

  $ hg merge default
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)

  $ hg branch

 set existing branch name where branch head is ancestor:

  $ hg branch bar
  abort: a branch of the same name already exists
  (use 'hg update' to switch to it)
  [255]

 set (other) parent branch as branch name

  $ hg branch default

Implicit merge with test branch as parent:

  abort: branch 'test' has one head - please merge with an explicit rev
  (run 'hg heads' to see all heads)

  $ hg up -C default

Implicit merge with default branch as parent:

  $ hg merge
  abort: branch 'default' has 3 heads - please merge with an explicit rev
  (run 'hg heads .' to see heads)
