new aa6d48f [TE] add threshold-based anomaly labeler (#5972)
aa6d48f is described below
commit aa6d48f183a6e7fd7c3c09e71bd165926da561aa
Author: Vincent Chen <[email protected]>

[TE] add threshold-based anomaly labeler (#5972)
This PR is the first part of adding an anomaly labeler for better alerting
ThirdEye users. It adds a labeling phase and a threshold-based labeler. The
next PR is to add the logic of translating YAML to JSON config.
