Couch search indexes (#8037)

* Defined search index for object names. Add index for searching by object type
* Feature detect if views are defined to support optimized search. If not, fall back on filter-based search
* Suppress github codedcov annotations for now, they are not accurate and generate noise.
* Allow nested describes. They're good.
* Add a noop search function to couch search folder object provider. Actual search is provided by Couch provider, but need a stub to prevent in-memory indexing
* Adhere to our own interface and ensure identifiers are always returned by default composition provider
