Ensure a request for telemetry happens in Condition Sets (#7592)

* request telemetry when subscribing to data in case we have cached subscription

* change back to >=

* revert

* update tests

* fixing tests

* add metadata

* fix test

* another mock required

* one more function needed

* attempt to fix some afterall errors

* add fixme for e2e test

* fail fast on request
