Add RDAP metrics for non-search endpoints

This CL uses the previously-defined RDAP metrics class to record basic metrics
for all RDAP endpoints, and handles testing of non-search endpoints. Searches
are more complicated, and will be handled in future CLs.

The default wildcard type is now INVALID rather than NO_WILDCARD.

A change to getMatchingResources() (adding an additional parameter) is also included in this CL, as it was needed to set the incompleteness warning type correctly.
