Generate zone property persist configs

Each zone object's hosted interfaces' properties can be configured to be
persisted or not at compile time. Those properties configured to be
persisted are set to be persisted after the initial value is set. When
this value doesnt change on a system, there's no need to persist it
since the initial value is compiled into the fan control application per
zone. Once this value is changed and therefore persisted, upon a
application restart, initially the value would be what's compiled in
until its configured again to be persisted and then restored.

Tested:
    Current property always set to what's persisted between restarts
    Nothing persisted when Current property doesnt change from default
