Add CometML Support

CO-1027

• Add CometMLLogger
• Along for the ride:
  • log hyperparameters for all loggers in entrypoint (not just wandb)

Manual/E2E Tests:

Local Custom Entrypoint

Comet results
WandB results for comparison

Local YAHP Entrypoint

CometML
WandB

Remote YAHP Entrypoint

CometML
WandB

Remote Custom Entrypoint

Remote Bert Run Results with Comet
Corresponding WandB run

• note: hyperparameters will be different because we are using Moin's custom entrypoint which explicitly logs hyperparameters to wandb

Are integration tests here feasible? Ideally we'd have something set up

Thank you for your Contribution. Left some comments. Also, do you have a plan to add a unit test for this change in tests/loggers/test_cometml_logger.py ?

[eracah]

Ok, @karan6181, @mvpatel2000, I added a unit test. Let me know how it looks and if this PR is ready for merge.

[mvpatel2000]

LGTM! Ideally we get integration tests at some point soon, but that's a later issue

[karan6181]

LGTM. Thank you!
