Stop single caches instead of all of them (#812)

* Revert OnSchemas change work

* Track schema changes

* Only stop a single GVK informer factory

* Add tests

* Rename crd to crdClient

* Rename s to sqlStore

* Don't wait for synced caches if request is canceled

* Move schematracker to pkg/sqlcache/schematracker

pkg/sqlcache/schematracker/schema.go
