feat(mdtest run/auto): support TAP (test anything protocol) test output
format and add --verbose flag for mdtest
mdtest now is able to report test output in TAP format. If --format
option is set to '--format=tap', mdtest will run
"pub run test --reporter json" to collect test output in json format
and transform json output into tap output on the fly. The default
behavior is '--format=none' which use the standard dart test output.
mdtest now support --verbose flag. If -v or --verbose is specified,
printTrace() will direct output to the standard error stream.
Otherwise, printTrace() does nothing.
Replace some print invocation with logging print.
