copying ConsistencyLevel from ThriftColumnFamilyQueryImpl when constructing AbstractThriftCqlQuery.
Merge pull request #398 from paulcichonski/master

Allow ColumnFamilyQuery#setConsistencyLevel to carry over to CqlQuery instances which it constructs.

Just making sure that you are aware of following:

1) In C* 1.1, if we need to set Consistency Level in Astyanax for CQL stmts, then it needs to be passed within each CQL statement (eg. Select * from CF1 USING CONSISTENCY QUORUM;). 

Although Astyanax api provides a way to pass in CL Level (after this pull request), for 1.1 ( or for CQL2), it gets dropped on the floor. And hence, it defaults to CL_ONE. (This is a limitation of C* 1.1 and CQL2. Not of Astyanax)

2) But with C* 1.2 (in CQL3) , we can set CL Level globally for CQL stmts (after this pull request).
