* Generic thermostat: add minimum cycle duration to keep-alive tests.
There was a bug in previous versions of the code, that would not execute
the keep-alive action if the minimum cycle duration hasn't passed.
This test verifies that the keep-alive action is executed correctly.
* Generic thermostat: added tests to verify that changing the
thermostat mode manually triggers the switch, regardless of
minimum cycle duration.
* Updated tests to use `common` module instead of the deprecated `climate`
