Removes activation config properties which aren't recognized by the resource adapter <code>activation</code>, from the
passed <code>activationConfigProps</code> and returns only those Properties which are valid.

@param resourceAdapterName   The resource adapter name
@param activation            {@link Activation}
@param activationConfigProps Activation config properties which will be checked for validity
