Improved resource access caching

* Smarter caching. ResourceAccess instances close after a timeout, if not reused.
* Introduced a start command to avoid race condition when sending
commands to a resource that is currently shutting down.
* We resend pending commands after we lost access to the resource
* unexpectedly.
