Merge branch '292906-rspec-feature-flags-fail-when-there-is-gitaly_-feature-flag-defined' into 'master'

Ignore `gitaly_*` feature flags in rspec:feature-flags check [RUN ALL RSPEC]

See merge request gitlab-org/gitlab!49799

gitaly_ feature flags are passed through to Gitaly
instead of being used in the Rails codebase.

When the feature flag is used only in E2E test
instead of rspec test, it would not be tracked
in 'tmp/feature_flags/*.used'.

Migrate button toggle for shared project runners to Vue

See merge request gitlab-org/gitlab!48452

To remove ambiguity with the current UI for enabling/disabling shared
runners in project settings, this MR replaces the button with a toggle
element. This is also consistent with our usage of toggles in the other
runner settings.

To do this, the UI has been ported to Vue while the POST endpoint
`toggle_shared_runners` has been modified to return the response in
JSON format.

The changes are gated by the `:vueify_shared_runners_toggle` feature
flag.
