[WIP] Integrate Clustering Code

[ch3njust1n]

1. Added condition to check if MLFLOW_TRACKING_URI env variable is set. If True, run clustering.
2. Created a new module called metric_tracking to host all the code
3. Updated ceph and clustering code to use the local storage module

For starters, make the code work only with the local storage module. The ceph storage can be added later in a different PR
