internal/gomote, internal/gomote/protos: add create instance implementation

This change implements the endpoint to create gomote instances for the
gomote GRPC service. In the process of implementing creates, various
other changes were needed:
- Refactoring the remote session pool.
- Extending the fake schedule used for testing.

Updates golang/go#48742
