Allow globbing in entity_id on entities for card

[Zocker1999NET]

If a card supports showing multiple entities like glance or entities, enabling support of globbing (*) would enable a more abstract UI definition without explicit listing of all entities wanted to show.

This would make things possible like: I want to show all alerts currently not idle so I know about and can disable the alerts or re-enable them if required:

- type: entity-filter
  entities:
    - "alert.*"
  state_filter:
    - operator: "!="
      value: idle
  show_empty: no
  card:
    type: entities
    title: Active Alerts

This would allow to write this once, forget about it, add an additional alert later on and the UI will do what I expected it to do, showing the new alert if it will go active.

Or another good example:

- type: glance
  entities: "device_tracker.max_*"

If used together with the FRITZ!Box integration and if I name all my personal devices (a.k.a. their hostnames) max_* or max-*, then new devices will automatically show up in the UI without changing my lovelace configuration.

not taking this away from a core HA discussion, but you know this is the exact scenario custom card auto-entities allows us to do?
