Move createAndSetTSUIDFilter() from TsdbQuery.java to Internal.java as it will be used by some other functions.
Fix Annotation.getGlobalAnnotations() to handle millisecond timestamps properly
Add Annotation.deleteRange() to remove local or global annotations for a given
time span.
Fix Annotations to normalize timestamps on second boundaries to 2 bytes instead
of 4 since we want to save space and avoid duplicates. This also allows all of
the functions to accept timestamps in seconds or milliseconds.
Add Annotation.timeFromQualifier() to parse the time from a qualifier given the
base time found in the row key.
Add a bunch of unit tests for the annotation range deletion and regular deletion
as well as the timestamp normalization.
