import: add a --secret option

Similarly to "hg commit", we add a --secret option to "hg import" for
committing with the secret phase. The option has no short form since
there already is a "-s" for "--similarity".

.. feature::

   ``hg import`` has a new --secret option for committing with the
    secret phase.
