Make custom hook dir configurable

Add a new configuration option, custom_hook_dir. When this is set, we will look for global custom hooks in: <custom_hook_dir>/{pre-receive,update,post-receive}.d/*

When this is not set, default to <ROOT_PATH>/hooks.

Relates to https://gitlab.com/gitlab-org/omnibus-gitlab/issues/1754. Will need a doc update in CE, too.

I've updated the VERSION file and created https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/8040 to update that in CE, along with the docs.

@smcgivern Let's tag v4.1.0 and push to all remotes (at least GitLab.com and dev)!

Pushed, thanks!
