Feature request: get config from MQTT, allowing multiple cards for one entity

[decramy]

I would like to have an overview of upcoming tasks in a dashboard and would like to use the 'auto-entities' card for that; it supports filtering and sorting to determ the entities to show. But the configuration of a task (like the timeout) could defer over multiple tasks.

Therefor I would like to hide the cards for the initial configuration in a separate dashboard, so the MQTT-topic will be generated, containing all configuration. Then, when I use the same entity again (in the main dashboard with upcoming tasks), this configuration could be gathered from MQTT and not again from Lovelace.

So; my feature request: if an entity already exists, try to get the config from MQTT. Then override this with the values given in Lovelace (like severity).
