Merge branch 'trigger_hooks_create_on_backup_restore' into 'master'

Trigger hooks create on backup restore

Number of users migrating from installation from source to omnibus get this issue. This can be fixed with a bash one liner but we already have a script that creates hooks in gitlab-shell. Added to gitlab:shell:install task call to `bin/create-hooks`. This script is idempotent which means it will only rewrite hooks if something changed.

Fixes https://dev.gitlab.org/gitlab/gitlabhq/issues/2208, https://github.com/gitlabhq/gitlabhq/issues/9101 and for the most part https://github.com/gitlabhq/gitlabhq/issues/8161
