New Custom Card : alarm time and toggle

[benbur98]

A new custom card that can be used to set the time and turn on/off an Alarm.
This brings together an input datetime helper and boolean helper.

I built this on top of @sildehoop 's custom_card_input_datetime, however, I couldn't add this boolean functionality without several breaking changes to that card - so a new one is required.
