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

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

Fixes #64

storage migrations

Enable GIT_TRACE/GIT_TRACE_PACKET/GIT_TRACE_PERFORMANCE by providing the git_trace_log_file config key

The value of the variable if present must be a writable absolute path. If it’s
not the case we log a proper message and not enable tracing to not throw output to the users.

- Required changes to GitLab Shell include the actual handling of the `git-lfs-authenticate` command and the retrieval of the correct credentials.

Track ongoing pushes and reject mv-storage commands if there are push running (after waiting some time)
