submodules: overhaul documentation
This patch aims to detangle (a) the usage of `git-submodule`
from (b) the concept of submodules and (c) how the actual
implementation looks like, such as where they are configured
and (d) what the best practices are.
To do so, move the conceptual parts of the 'git-submodule'
man page to a new man page gitsubmodules(7). This new page
is just like gitmodules(5), gitattributes(5), gitcredentials(7),
gitnamespaces(7), gittutorial(7), which introduce a concept
rather than explaining a specific command.

The other repository has its own history, which does not -interfere with the history of the current repository.

Directories -that come from both projects can be cloned and checked out as a whole -if you choose to go that route. +For more information about submodules, see linkgit:gitsubmodules[7].
