Add columns to result handler for row level metadata

[nehanene15]

Currently, DVT execution does not provide a response code with the run_id on command line execution, the user needs to go into BQ and search the execution results to find the appropriate run_id. This becomes more cumbersome when multiple executions of DVT is done at same time. DVT should log the run_id in standard output.

Add columns in the result handler for applied filters (if any), custom query applied at source/target, and columns used for hashing/concat
