Resolve "Remove "Build failed" TODO if it has been auto-retried"

Closes #38236

See merge request gitlab-org/gitlab-ce!14869

We can currently reduce the number of times we specify the tag of a
given example group by moving them hoisting them up one level to the
containing `feature`

This was added as part of the previous filtering via RSpec::Config.  It
should have been removed previously as part of moving the logic to
specify the tags we wanted in Specs::Runner

Fix diff parser so it tolerates to diff special markers in the content

Closes #34431

See merge request gitlab-org/gitlab-ce!14848

When a build is retried automatically, we close any open todos. However, we do
that _before_ creating a new build failed todo.

To solve this, we check if the build is retried before creating the todo. We
also ensure that the build _instance_ has the correct attribute set, without
needing to reload it from the database.

It's adding additional potentially confusing behaviour to derive test
tagging from the file path, as it's not immediately apparent where that
lives when considering the tests in isolation.  Instead, just explicitly
tag.

* Remove the tagging of examples based on :file_path
* Explicitly tags scenarios as :core, or :mattermost

Fix confusing double usage of 'metadata'

Here we convert Specs::Runner#rspec to use keyword arguments[1] and pass
named parameters rather than a pre-processed array of cli switches.
This allows parameter to cli logic to live just in Specs::Runner.

Update Vuex version

Closes #39096

See merge request gitlab-org/gitlab-ce!14868

Entrypoint is intended as a base class, so mention that in the comment.

As suggested by Grzegorz, we can be more declarative in our
configuration of the tags the Entrypoint cares about

Here we add a tags method to the entrypoint class, and use that to
declare the tags an entrypoint is interested in (:core for the existing
Test::Instance, :core and :mattermost for Test::Integration::Mattermost)

We declare everything in specs/features that isn't in
specs/features/mattermost, to have the tag :core, though that clean up
better if we move the integration tests out of specs/features.
