host:port from environment variables without quotes #9614.
Prior to this change, when overriding a host:port config value from environment variable, one has to quote it as:
env EMQX_BRIDGES__MQTT__XYZ__SERVER='"localhost:1883"'.
Now it's possible to set it without quote as env EMQX_BRIDGES__MQTT__XYZ__SERVER='localhost:1883'.
