We're checking if octavia_amp_availability_zone is defined, while the variable is defined in defaults, so there is no clean way to undefine the availability_zone except to use config overrides and define to none. So whe change condition in a way to allow empty value to be treated as False which would result in availability_zone being undefined in the config. Change-Id: I86ffd71d6791dec700c381b695ab5a4bca8051a3
