Add --cpu-rt-runtime to allow Docker allocate real-time CPU time (#1235) (#1236)

Browse Source 
* Add --cpu-rt-runtime to allow Docker allocate real-time CPU time (#1235)

* Enable Supervisor's CPU bandwith allocation feature (#1235)

Since we have CONFIG_RT_GROUP_SCHED enabled in the Home Assistant OS
kernel the Supervisor needs to enable CPU bandwith allocation for
Add-Ons which need real-time scheduling. Set the appropriate environment
variable.
