[MOB-9381] - Push platform Configuration for iOS

Add pushPlatform config for iOS.
To use, developers will have to set the config variable as follows:
config.pushPlatform = IterablePushPlatform.production

or it can be .sandbox or .auto as well.

This will allow to manually set the platform type if automatic is not working.
