Add knapsack qa report and use it to run tests in parallel

Use the RSpec runner with knapsack

The way the Knapsack runner uses exec to start rspec seems
incompatible with the way we expect it to work. Plus, it requires
specifying KNAPSACK_TEST_DIR.

Instead, we use knapsacks AllocatorBuilder to select the spec
files to run, and then start rspec as normal, via
RSpec::Core::Runner.run

This also means we can incorporate tags.

Let the job run automatically

Include KNAPSACK_TEST_FILE_PATTERN in vars

Check all defined knapsack env vars before requiring knapsack

Docs feedback: Redis Troubleshooting Replication

Closes #60782

See merge request gitlab-org/gitlab-ce!28936

When a Group is missing a route, the migration failed previously with a
`Invalid single-table inheritance type` error. To fix this, we can
disable STI for the migration class because we don't need to know about
the type to do this migration. Besides, currently Group is the only type
used in the type column.

Closes https://gitlab.com/gitlab-org/gitlab-ce/issues/58714

This matches the version used in Gitaly and avoids potential
version conflicts when multiple versions are installed.

Resolve "Tooltip Consistency"

Closes #61821

See merge request gitlab-org/gitlab-ce!28839

On edit-button simply set position to top.
Made this change directly in template since edit-button
is only used in one place.

Had to wrap the comments toggle button in span tag to make
tooltip show even when disabled as per bootstrap-vue docs.
https://bootstrap-vue.js.org/docs/components/tooltip#overview

Note: Also changexc button to gl-buttonto be consistent
with rest of file.
