Enhance the various update_*_test_checks.py tools to allow filtering the tool output with regular expressions. The --filter option will emit only tool output lines matching the given regular expression while the --filter-out option will emit only tools output lines not matching the given regular expression. Filters are applied in order of appearance on the command line (or in UTC_ARGS) and the first matching filter terminates the search. This allows test authors to create more focused tests by removing irrelevant tool output and checking only the pieces of output necessary to test the desired functionality.
