Description

The SubscribeFeedStatement in the AQL parser looks hackish:
https://github.com/apache/incubator-asterixdb/blob/master/asterix-aql/src/main/java/org/apache/asterix/aql/expression/SubscribeFeedStatement.java#L72

The metadata access as well as the additional processing logic should be refactored out of the parser.
