def sampleRecord(record: Record): Boolean

Decides if we should record this record or not.
Decides if we should record this record or not. If this trace is marked as not sampled we just throw away all the records If this trace is marked as None (no decision has been made), consult the sampleTrace impl
returns
true if we should keep it, false for throw away
