Rewritten miq_ae_class view to HAML + added gettext calls

Fixed spec/requests/ authentication specs

- Update session_store to use :memory instead of default cookie_store for tests,
eliminating the 4K limit that was giving us the 500's.
- Needed to specify HTTP_USER_AGENT for a couple of tests in auth_spec.rb
PR Review Updates

- Simplified check in session_store initializer
- Reverting auth_specs tests as earlier.
- Updating request_referer_service.rb to handle empty referer
For MiqAeField and MiqAeValue use build+save instead of create!

This PR is based on the Active Record/Postgres.

For Git based Automate model the MiqAeField and MiqAeValue are saved
in the class and instance yaml files and are not separate tables like
in ActiveRecord. Build followed by a save allows us to write just once
into the file as opposed to writing the file several times once a value
or field is saved.
