WIP: set 16 core runners to oci gh arc runners

[jeefy]

Description

CNCF has hosted ephemeral GitHub runners in Oracle that we're wanting projects to use rather than the GitHub hosted ones, which are now incur a cost to use. This PR is currently a WIP to work through any tests that break or dependencies that may be missing. <3

Please direct any questions to myself, @krook and @RobertKielty

Documentation

• Apply the release notes (needs details) label if users need to know about this change.
• New features should be documented.

Seems like there is a consistent failure:

Warning: apt-key is deprecated. Manage keyring files in trusted.gpg.d instead (see apt-key(8)).

When installing dependencies, specifically this:

@frouioui thank you for letting us know. I will look at this now.

Edit : @jeefy added dirmngr on this cncf/automation#53 to the image which fixed the error that you reported.

We can see the workflow getting the key to the latest MySQL key repohere

Looks like all but one test is consistently passing. Ran into an interesting scaling issue with ARC/K8s and disk pressure causing flakes because the runner pod was getting evicted.

Don't know why that last one is failing, but I suspect it's some difference in environments still.

The failing tests in onlineddl_vrepl_suite are consistent. These are always:

2025-03-04T23:30:46.7729927Z     --- FAIL: TestVreplSuiteSchemaChanges/alter-charset-non-utf8 (2.05s)

Failing with this error:

vreplication: terminal error: task error: failed inserting rows: Incorrect string value: Cannot convert string "átesting" from latin1 to latin2 (errno 1366) (sqlstate HY000)

The runners are using mysql 8.0.41, same version as our standard runners. I'm not sure if there's any environment change here, as our standard runners are perfectly happy with the test (example).
