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.
