Key: GORA-411

Priority: Minor
Fix For: 0.7
NUTCH-1679 need to check if there exists some rows and they are proposing to
use {{store.get(TableUtil.reverseUrl(url)))}}.
This will have a considerably impact on performance since every column will
be fetched.
Some datastores implements a call to just check if a row exists (like HBase)
so no data is transfered by network.
If a datastore can't handle an exists call, can default to a get.
