ci: PR tests take too long (17m)

[codefromthecrypt]

Currently, PR tests take too long to verify.. 17 minutes. Most of the very long tests use docker. Besides that is dubbo which can be longer than 2 minutes to complete despite not using docker. We should bump the heavy tests into separate jobs, at least the docker ones.

Feature

Split the docker tests into separate jobs, like zipkin does.

Rationale

We should be able to get test execution speed down as they aren't all sequential. less time to re-run a flakey test.
