Add option to support jdk repo and branch

[sophia-guo]

Currently run-aqa run latest openjdk tests for all jdks. That is jdk8 for all hotspot jdk8. Similar to all other version and all openj9 jdk.

It would be nice if we add option to support jdk repo and branch so we can run each jdk's corresponding tests and the run-aqa tests can be part of openjdk repo's PR tests.

We could do this ether by passing the environment variable or adding the options. Adding the options would be more easy and clear. Similar to the draft PR #32
