[PATCH 0/3] Introduce `submodule interngitdirs`

[Stefan Beller <sbeller@google.com>]

The discussion of the submodule checkout series revealed to me that a command
is needed to move the git directory from the submodules working tree to be
embedded into the superprojects git directory. 

So I wrote the code to intern the submodules git dir into the superproject,
but whilst writing the code I realized this could be valueable for our use
in testing too. So I exposed it via the submodule--helper. But as the
submodule helper ought to be just an internal API, we could also
offer it via the proper submodule command.

The command as it is has little value to the end user for now, but
breaking it out of the submodule checkout series hopefully makes review easier.

Thanks,
Stefan
