Add common SOS GetCap Tests (OGC reference implementation and NcSOS)
SOS GetCapabilties requets should not send a "version" parameter per spec

acceptVersions is acceptable
Implement SensorML 1.0 per the OGC spec

The exising implementation was a one-off NDBC representation of SensorML.
This implementation tests the DescribeSensor SensorML response from the OGC
reference implementation of SOS (52N) and as well as NDBC's DescribeSensor
for a station.
