MQTT `retain` flag should be applied only to `publish` operations

[KhudaDad414]

Reason/Context

The retain flag in MQTT binding should only be applied when the type of operation is publish. It can be applied to publish and subscribe according to the current bindings.

Solution

Remove subscribe from the Applies to column in the operation binding object.
