[ASTERIXDB-2227][ING] Enabling filitering incoming data in feed

- user model changes: yes
  Add syntax support for specifying predicate in connect feed
- storage format changes: no
- interface changes: no

In some use cases, a user may want to filter the incombing data with
certain attributes. One example can be only store the incoming tweets
with geo locations. This patch enables the <WHERE> clause in connect
feed statement. User can subset the incoming data using following

 connect feed feeds.TweetFeed to  dataset Tweets3 using policy `Basic`
 WHERE id NOT LIKE 'nc1:10%' OR username = 'BronsonMike';
