Ensure minimum replicas >1 with HPAs
Closes #447 (closed)
Added HPAs for:
- gitlab-shell
- registry
- unicorn
Bumped default replicas to 2 for sidekiq(s)
Didn't touch workhorse and pages since they're dead code
Didn't change task-runner since it is utility and not HA
Didn't touch gitaly because #432 (closed)
Didn't touch gitlab-runner because that's more of an explicit choice by the end user
