Cole Walker 939b72d8b1 [PTP] Add clockClass tracking and multi ptp instance support 
Adds notification functionality for PTP clockClass data and re-works the
overall PTP sync status to allow for multiple ptp4l instances to be
tracked. Each ptp4l instance reports its own sync status and clockClass.

This change moves several static functions out of ptpsync.py and into
the PtpMonitor class. The remaining static functions have been moved
into utils.py

This change retains backwards compatibility allowing for v1 PTP
notifications and subscriptions to continue working while also providing
the v2 functionality required by the ORAN Notification standard.

This change also provides an override value for the logging level
exposed via a helm chart override.

Testing:
PASS: GET and Subscribe functions for each notification type
PASS: Multiple PTP instance support
