Add a "master alarm" entity

[Jalle19]

There are a ton of different alarms, so it can be difficult to see if any of them are active. We could add a master alarm that is on when any alarm is on, and off when all alarms are off.

@JohanElmis @tomrosenback what do you think about this?

A have grouped the alarms in HA, this give same effect as described here. I am fine with adding it here.

@tomrosenback how did you group them?

Like this I have it configured with the 2.1.0 release in a separate groups.yaml file

eda_alarms: name: EDA alarms icon: mdi:exclamation-thick entities:

• binary_sensor.eda_coolingfault
• binary_sensor.eda_emergencystop
• binary_sensor.eda_firerisk
• binary_sensor.eda_heaterfault
• binary_sensor.eda_heaterpressureswitch
• binary_sensor.eda_ltofault
• binary_sensor.eda_hpfault
• binary_sensor.eda_inletfanpressureabnomaly
• binary_sensor.eda_inletfilterdirty
• binary_sensor.eda_outletfanpressureabnomaly

Nice, didn't know entities could be grouped together like that. I'll try it out, sounds better than hacking a "master alarm" into this software.
