Currently when specifying the `--depth` option to the 'submodule add'
command, it can only create a shallow submodule clone of the currently
active branch from the cloned repository. If a branch is specified using
the `--branch` option, and the `--depth` option is also specified, the
'submodule add' command will result in an error as the branch will not
be present in the cloned repository. If a repository is shallowly cloned
as a submodule, there is no way to specify that the shallowly cloned
submodule should setup remote-tracking branches.
Added the ability to shallowly clone any branch as a submodule, not just
the current active branch in the cloned repository.
Added support to the 'submodule add' and 'submodule update' commands to
handle `--no-single-branch` option, which is in turn passed to the clone
command in order to setup remote-tracking branches in the shallowly
cloned submodule.
