Remove baseline_models dependency

[amrit110]

Currently, some of the drift_detection use cases import implemented models from the https://github.com/VectorInstitute/cyclops/tree/main/cyclops/monitor/baseline_models directory. This should be removed and instead be replaced with model implementations from https://github.com/VectorInstitute/cyclops/tree/main/cyclops/models.

• Remove use of models from the above mentioned baseline_models directory and replace with those in models.
• Remove baseline_models from the codebase
• Test if the migration works as intended.

That should work, The only caveat is the optimizer.py using for the retrainers. But, I could place that in the utilities for the monitor package.

I'll create a branch for this now and let you know if there's any issues.
