• Refs https://github.com/influxdata/flux/pull/5172

Required checklist

• [ ] Sample config files updated (both /etc folder and NewDemoConfig methods) (influxdb and plutonium)
• [ ] openapi swagger.yml updated (if modified API) - link openapi PR
• [ ] Signed CLA (if not already signed)

Description

In https://github.com/influxdata/flux/pull/5172 various tests which have been skipped long-term were repaired. This diff removes them from the skip list during the flux integration tests run as a part of CI here.

Context

Adds additional coverage to the flux integration tests.

Affected areas (delete section if not relevant):

CI, specifically test selection for fluxtest.

Note for reviewers:

Check the semantic commit type:

• Feat: a feature with user-visible changes
• Fix: a bug fix that we might tell a user “upgrade to get this fix for your issue”
• Chore: version bumps, internal doc (e.g. README) changes, code comment updates, code formatting fixes… must not be user facing (except dependency version changes)
• Build: build script changes, CI config changes, build tool updates
• Refactor: non-user-visible refactoring
• Check the PR title: we should be able to put this as a one-liner in the release notes

Tests are still failing, but it looks like this is because the fixes were in flux v0.182 or v0.183, but we still have v0.181 here.

:sweat_smile: bit of a shame to need to inline these, but I'd rather keep the coverage until we can work out something better.
