Add Risco communication delay (#101349)

* Add optional communication delay in case a panel responds slow.

* Add migration test

* Connect by increasing the communication delay

* Update init to use option instead of config

* Updated strings

* Fix migration and tests

* Review changes

* Update connect strategy

* Update tests

* Changes after review

* Change typing from object to Any.

* Add test to validate communication delay update.

* Move test to separate file

* Change filename.
