Way to make entities persist?

[skynetforcats]

Wondering if there is a way to make discovered entities persist. I have some sensors that only update once or twice per day and they seem to cause trouble if I want to use the states for other template sensors etc.

I think it might be possible to accomplish this to some extent by supporting the entity registry. When I get some time to experiment, I will prototype support for that. It will only work for entities with a unique_id.
