All synchronization states of LOCKED, HOLDOVER, and FREERUN need to be
all-caps in the state change event notifications. This is a requirement
of O-Cloud Notification API Specification for Event Consumers -
O-RAN.WG6.O-Cloud Notification API-v03.00.
Changed the JSON message body of the Sync OS clock, Sync Sync State,
GNSS sync status and Sync PTP Lock State to ensure all caps.
Updated ptp-notification V2 documentation to reflect the notification
message changes.
Test Plan:
PASS: Build container image
PASS: Manually deploy image and test with v2 client
PASS: Clycled through states
PASS: Restarted ptp-notification application and v2 client
received the events after starting the PTP notification pods.
PASS: ptp-tracking unit tests
