Similar to `git submodule foreach` the new command
`git submodule foreach_parallel` will run a command
on each submodule.
The commands are run in parallel up to the number of
cores by default, or you can specify '-j 4' tun just
run with 4 threads for example.
One major difference to `git submodul

This runs a command on each submodule in parallel and should eventually
replace `git submodule foreach`.
There is a new option -j/--jobs (inspired by make) to specify the number
of parallel threads.
The jobs=1 case needs to be special cases to exactly replicate the current
default behavior of `gi
