ST_ClusterDBSCAN should return a NULL id for "noise" inputs

Description

Currently, the function returns a cluster ID for all inputs; the user can then filter after the fact to ignore cluster IDs with fewer than X members. This is cumbersome and unlikely to be useful, and leaves gaps in the sequence of final cluster IDs. The function should instead return a NULL cluster ID for inputs that are not in a cluster.
