[Feature]: Add battery indicator to lock card

[thezboe]

Is your feature request related to a problem?

I like to be able to see the battery level of things in plain sight at all times so I can be aware when they are running low. The lock card is wonderful, except there isn't a way for me to see the battery status of the lock (what kind of smart lock doesn't run on batteries?).

Describe the solution you'd like

1. Add a battery icon with an optional battery entity option for easy viewing.
2. Allow templating on the main or secondary lines so I can just put the battery percentage on one of those lines.

Describe alternatives you've considered

The only other way would be to recreate the existing lock card as a template card, which somewhat defeats the point.

Additional context
