Add ability to provide source object ID in search endpoints

[korikuzma]

Currently, we run query parameters (variation, disease, therapy, gene) through our normalizers. I think we should allow for source identifiers (such as civic.vid:12) to be searched. I'm not sure if we would want to create a separate endpoint for this or add to existing enpoints

Yeah, this is interesting. Since we know the source ID patterns in advance, maybe we could do a quick regex on each term as it comes in to determine whether it gets sent to a normalizer or incorporated directly into a query (optionally disable-able?).
