Adds an ops feature flag so we can activate only on GitLab.com,
updates the auth_helper to allow GTM for signed in users, updates
the controller to pass the frontend feature flag, and adds an RSpec test
to verify behavior.

Add Terraform States to Backup and Restore tasks

See merge request gitlab-org/gitlab!63347

Reuses standard file upload storage to cover Terraform
states backup

Adds a seed for generating terraform state files
under each project

Manual testing (in local GDK env):

- Verfied seed addition via `bin/rake db:seed_fu FILTER=terraform`
- Verified seed addition is repeatable, with no-ops if versions
  pre-exist
- Created backup: `bin/rake gitlab:backup:create`
- Verified output shows up:

```
2021-06-05 23:48:54 +0530 -- Dumping terraform states ...
2021-06-05 23:48:54 +0530 -- done
```

- Verified tar contains terraform_state.tar.gz
- Verified terraform_state.tar.gz carries content
- Destroyed all records: `Terraform::State.destroy_all`
- Deleted all files: `rm -rf shared/terraform_state/*`
- Performed restore: `bin/rake gitlab:backup:restore`
- Verified `Terraform::State.all` shows back older records
- Verified association of builds to some of these records
- Verified `shared/terraform_state/` is repopulated
- Verified `Terraform::StateVersion.each do |sv| pp sv.file.read end`
  works and shows the seed-added data
- Verified skipping of `terraform_state` keyword works:

```
2021-06-06 00:11:33 +0530 -- Dumping terraform states ...
2021-06-06 00:11:33 +0530 -- [SKIPPED]
```

Verified with same workflow as above (backup, destroy, delete,
then restore) that skipped backup variant does not contain
`terraform_state.tar.gz` and does not show up those files after
restore

Miscellany:

- Adds a missing test for LFS backups
- Adds File operation fixes to neighboring tests
  so when they fail RSpec is able to show diffs
- Modified test validates unknown SKIP values not
  breaking backups
  - This is useful to catch any regressions during
    upgrades where pre-installs scripts may refer
    to a new SKIP value that isn't recognized by
    the old version

[ci skip]

This adds a RuboCop rule that disallows the usage of
`SomeModel.establish_connection`, as this pattern can break database
configurations and slows down the tests.
