Split "tsd.core.meta.enable_tracking" into three options to allow for greater
TSD tuning. Adding tons of callbacks to the data point AtomicIncrement can
eat up a lot of resources. Instead, the user can still issue AIRs but leave
the TSMeta creation for the dirty flag table processor. The user can also
turn off UIDMeta creation. The new options are now:
"tsd.core.meta.enable_realtime_ts" to generate TSMeta objects in real-time,
"tsd.core.meta.enable_realtime_uid" to generate UIDMeta objects in real-time,
"tsd.core.meta.enable_tsuid_incrementing" to track data points.
