Add additional RAVEN-related labels
There is a need for additional labels to indicate states in GraceDB and resolve race conditions:
-
COMBINED_SKYMAP_READY
: Combined skymap is available. -
SOG_READY
: A coincidence should trigger a speed of gravity measurement.
The code changes that require these labels are emfollow/gwcelery!864 (closed) and emfollow/gwcelery!890 (merged) respectively.
