Add Arm Max service to alarm_control_panel

[abarbaccia]

Alarms typically have different ways of arming. The two most basic forms are:

1. Arm Home -- arms perimeter only (no motion sensors)
2. Arm Away -- arms both perimeter + motion sensors

In addition, there are more secure versions for each of these modes, where there is no entry delay. In these circumstances, when someone trips the alarm, the siren goes off immediately (vs. beeping first and allowing someone to enter a code to disarm). These modes are:

3. Arm Night -- same as arm home (perimeter only), but no entry delay
4. Arm Max -- same as arm away (perimeter + motion), but no entry delay. Sometimes this is also called "vacation mode"

We currently implement #1-3 in the alarm_control_panel architecture. This issue requests to add functionality for #4.

This architecture issue is old, stale, and possibly obsolete. Things changed a lot over the years. Additionally, we have been moving to discussions for these architectural discussions.

For that reason, I'm going to close this issue.
