Michael Ho cbcda93dfb IMPALA-3334: Fix some bugs in query options' parsing. 
This change fixes two problems:

1. The query options OPTIMIZE_PARTITION_KEY_SCANS and
   DISABLE_STREAMING_PREAGGREGATIONS are both boolean
   so they should accept 'true' and '1' as input values.
   Previously, these two options are treated as int and
   value such as 'true' doesn't work with them.

2. The break statement in the case statement of the option
   SCAN_NODE_CODEGEN_THRESHOLD was 'stolen' by the option
   DISABLE_STREAMING_PREAGGREGATIONS when it was added.
   This change adds the missing break statement back for
   SCAN_NODE_CODEGEN_THRESHOLD.
