Collections that rely on integration websocket API should wait with refreshes after reconnect

[balloob]

The websocket API is one of the first integrations to load in Home Assistant. This means that during a restart, the frontend is able to reconnect. Reconning triggers a refresh of all subscribed collections.

For things like the energy collection, this is causing warnings in the logs because the energy websocket APIs are not online yet.

Collections need to be able to specify an integration that needs to be loaded before refreshing. We should also raise when subscribing.
