The generic _shardsvrParticipantBlock command, used to enter and exist the recoverable critical section, only works with a collection names as a resource.

Since with SERVER-70660 the support for the recoverable critical section was extended to databases, this command should be enhanced to support database as well.

Currently, passing a database as a resource name, the command parser (generated by the IDL parser) asserts as the string <db>. is not recognized as a valid collection name.
