Negated queries

Description

The ability to send special 'negated' queries, so that we can ask that we specifically don't get a dataset, without needing to specify all of the datasets that we do want.

For instance, if we already have EIT info, and now we want to go back and get all all EUV images that AREN'T from EIT, we might ask for

<instrument>! EIT</instrument>
<nickname>EUV image</nickname>

Something of this nature may be necessary as we begin interconnecting VxOs, so that EGSO can call us, and specify 'provider != EGSO' or the equivalent.

The good news is that EGSO served catalogs, and used us for data, and this was never an issue.

This might be possible w/ MongoDB ... not sure if can be done in registry only, or requires changes on some data providers.
