Add support for Gitaly feature flags

See merge request gitlab-org/gitlab-shell!351

gitaly#1846

Gitaly does not store or remember feature flags. We must pass them in as
metadata on each request. This MR adds plumbing to pass Gitaly feature flags
supplied by gitlab-rails to the Gitaly server as gRPC request metadata.

Remove deprecated create-hooks script

See merge request gitlab-org/gitlab-shell!342

This commit duplicates a small amount of Ruby code that is run at build
or install time. Over time, it would be nice to remove the dependency
on Ruby for these steps, but the focus right now is on run-time.

We'll be removing lib/* from gitlab-shell very soon, and these commands
need to keep working when we do.
