Add mode parameter to select strategy for action types execution

Feature Request

Is your feature request related to a problem?

As of now, when an action type (or a list of them) is being executed, and another one gets fired, the previous gets cancelled and a new one is executed. User does not have the ability to choose the strategy.

Describe the solution / feature you'd like

The proposed solution is to add a new parameter mode with a similar functionality of the Home Assistant automation modes. The idea would be to leave single as default to have a similar behaviour than HA automations.
