Jedis Test improvements

[gerzse]

Improve the testing area in Jedis, across two directions:

• get more code coverage;

• run against different flavors of Redis, and don't build Redis from source.

• Don't rely on compiled Redis #3710

• Support Redis Enterprise in CI #3711

• Tag tests per Redis environment (not version) #3712

• Remove support for Redis unstable #3713

• Integrate JUnit reporter in the CI, dorny/reporter #3714

• Proposal: Mark jedis test cases based on compatible redis versions #3471

• Add unit tests for Bloom filters #3709

• Add unit tests for Timeseries #3708

• Flaky tests #2367

• CI for different Redis versions (4.0, 5.0, 6.0, 7.0...)  #3410

• Check tests that force Redis failover, maybe separate them #3715

• Add pre-commit linting to the repo #3716

• Check tests that are commented out #3717

• Speed up slow tests, or separate them out in their own jobs #3718

• Run parallel jobs #3719

• Ensure local development can run tests easily #3720

• Please document your gpg keys #3125

• Make tests idempotent #3721
