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

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

On GitLab.com, we see that cron jobs sometimes don't run. This appears to be
because the process that polls for current cron jobs only has a 60 second
validity period, so if (for whatever reason) it misses those 60 seconds, we have
to wait until the next execution.

For the usage ping, this is particularly problematic, as that's only scheduled
to run once a week.

Changing it to run for every minute in a 10 minute period should work around
this, if the above diagnosis is correct. The job itself obtains an exclusive
lease for 24 hours, so rescheduling in quick succession is safe.

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.
