Make a QueryImage command from OTA Requestor to OTA Provider

* Make ota-provider-app and ota-requestor-app compilable on Mac
* Remove self commissioning code from ota-requestor-app
* Add a parameter for IP address for OTA Requestor to use for creating secure session
* Add a parameter for fabric index for OTA Requestor to use for creating secure session
* Add a parameter for time to wait for OTA Requestor to initiate a QueryImage command from startup
