for-each-repo: optionally keep going on an error

Browse Source 
In https://github.com/microsoft/git/issues/623, it was reported that
the regularly scheduled maintenance stops if one repo in the middle of
the list was found to be missing.

This is undesirable, and points out a gap in the design of `git
for-each-repo`: We need a mode where that command does not stop on an
error, but continues to try running the specified command with the other
repositories.

Imitating the `--keep-going` option of GNU make, this commit teaches
`for-each-repo` the same trick: to continue with the operation on all
the remaining repositories in case there was a problem with one
repository, still setting the exit code to indicate an error occurred.

@ -42,6 +42,15 @@ These config values are loaded from system, global, and local Git config,
as available. If `git for-each-repo` is run in a directory that is not a
Git repository, then only the system and global config is used.
--keep-going::
Continue with the remaining repositories if the command failed
on a repository. The exit code will still indicate that the
overall operation was not successful.

Note that the exact exit code of the failing command is not passed
through as the exit code of the `for-each-repo` command: If the command
failed in any of the specified repositories, the overall exit code will
be 1.
