This allows to configure fetching and updating in parallel without having the command line option. This moved the responsibility to determine how many parallel processes to start from builtin/fetch to submodule.c as we need a way to communicate "The user did not specify the number of parallel processes in the command line options" in the builtin fetch. The submodule code takes care of the precedence (CLI > config > default).
