sync: add option to skip manifest update

Browse Source 
The use case is any situation where your manifest does
not exist on server, but where you still want to do
full sync for the projects, without having your
workspace manifest switched to other branch or
forwarded to latest or similar.
This allows syncing to a historical manifest in git log,
that does not have a branch, as well as when integrating
something together that has not been pushed upstream yet.
Changes can also exist locally on a manifest that is
behind head, meaning not requiring rebase to latest.

Tested using:
  $ cd .repo/manifests/
  $ git checkout <any hash 1>
  $ <do local modifications>
  $ repo sync --no-manifest-update
  $ git checkout <any hash 2>
  $ repo sync --no-manifest-update
