graft: add no-commit mode (issue5631)

This patch adds a new flag --no-commit in graft command. This feature
grafts the changes but do not create commits for those changes, grafted
changes will be added in the working directory. Also added tests to reflect
the expected behavior.

============================================
Testing obsolescence markers push: Cases B.5
============================================

Mercurial pushes obsolescences markers relevant to the "pushed-set", the set of
all changesets that requested to be "in sync" after the push (even if they are
already on both side).

This test belongs to a series of tests checking such set is properly computed
and applied. This does not tests "obsmarkers" discovery capabilities.

Category B: pruning case
TestCase 5: Push of a children of changeset which successors is pruned

B.5 Push of a children of changeset which successors is pruned
==============================================================

.. This case Mirror A.4, with pruned changeset successors.
