Update CI to use Compaction Planner

[milleruntime]

Continuous Ingest is still using BasicCompactionStrategy, which has been deprecated in favor of the new compaction code. This needs to be replaced with a CompactionPlanner, most likely DefaultCompactionPlanner will work fine. This may just be a configuration change.

This would be great to do for the 2.1 release testing.

It may be as simple as changing these properties:

It does seem like the tables default to use DefaultCompactionPlanner. Do you think its a good idea to still try and set them explicitly in the props file or just remove the deprecated BasicCompactionStrategy? @milleruntime
