Currently the submodule.<name>.url config option is used to determine
if a given submodule exists and is interesting to the user. This
however doesn't work very well because the URL is a config option for
the scope of a repository, whereas the existence of a submodule is an
option scoped to the working tree.
In a future with worktree support for submodules, there will be multiple
working trees, each of which may only need a subset of the submodules
checked out. The URL (which is where the submodule repository can be
obtained) should not differ between different working trees.
It may also be convenient for users to more easily specify groups of
submodules they are interested in as apposed to running "git submodule
init <path>" on each submodule they want checked out in their working
tree.
To this end, the config option submodule.active is introduced which
holds a pathspec that specifies which submodules should exist in the
working tree.
