Replace fixed number of bloom filter tables with the support for dynamic number of tables
Get bloom filter tables from SQL metadata
Check if regex patterns stored in each bloom filter table matches archive query search term tokenized values
Left join only those bloom filter tables that had pattern match
Filter query using bloommatch function for each logfile or check if filter is null on all joined tables
Some refactoring on com.teragrep.pth_06.planner.walker and tests

All new classes now have only final values and public methods always return the same value after instantiation (weakly immutable). I included some refactoring of old classes but I think the project would require a larger refactoring to be more object-oriented. Made project issues regarding refactoring
