Currently, in the event that a submodule's upstream URL changes, users
have to manually alter the URL in the .gitmodules file then run
`git submodule sync`. Let's make that process easier.
Teach submodule the set-url subcommand which will automatically change
the `submodule.$name.url` property in the .gitmodules file and then run
`git submodule sync` to complete the process.

Right now, submodule.<name>.url might be the only thing that gets
synched down to .git/config of the submodule; we may not learn any
more things that needs "edit in .gitmodules and then run sync". Can
we sately say that "sync" is now obsolete and what it has been used
for can now be done with "set-url"? In other words, does "set-url"
makes "sync" unnecessary and deprecated?
Or is it expected that we would learn more things end users can edit
in .gitmodules and run sync to propagate necessary pieces of
information down? If so, do we want to add an extra command like
set-url for each of these new things, or do we tell users "if you
are editing url, use set-url, otherwise edit .gitmodules and run
sync"? If the former, that would make the set of subcommands quite
noisy, and if the latter, the users need to learn two things,
i.e. it is not making it easier but harder to learn the system.
There is nothing _wrong_ to introduce the new subcommand per-se, but
given that the URL should not change that often, and due to above
concerns, I am not sure if I want to back this change.

"sync" isn't deprecated quite yet. If upstream edits the .gitmodules and
we pull in the change, then we still need to run "sync" to update our
.git/config.

I was running under the assumption that we weren't planning on adding
new information to .gitmodules. I don't think we'll be making changes to
the submodule file format without careful thought so _if_ that ever
comes up, we should discuss it then but I don't think it's a discussion
that's going to happen any time soon, if ever.
Either way, though, the sync workflow isn't going away so users still
need to know how to do that (unfortunately). We'll just add a
convenience function on top to make people's lives easier but it's not
strictly _necessary_ to use "set-url".

I think it changes often enough to cause problems. Seems like at least
936 people on StackOverflow agree with me[1].
I think that the problem is that it's a common enough use-case but not
common enough that people often forget to "sync" after editing the
.gitmodules. I know that it's bitten me the few times I've done this and
I've had to go back to that SO post each time.

Which means that far from deprecating "sync", we should strive for
imprinting the need for the use of the subcommand deeper in users'
minds. I wonder if it makes sense to make sure that .gitmodules
file starts with something like
# Note that after updating this file, you may want to
# run "git submodule sync" so that the URL for the remote
# repository etc. are propagated down.
when we create it (via, say "git submodule add")? Or alternatively,
warn the users when "git status" notices a local modification, or
something along that line?
