run-tests: add --with-chg option to run tests using chg

Unlike --with-hg=/path/to/chg, this option allows us to start and clean up
command servers in isolated environment. And we can specify the hg command
as well as the chg command.

if os.environ.get('COVERAGE_PROCESS_START'):

        import coverage
        import random

        # uuid is better, but not available in Python 2.4.
        covpath = os.path.join(os.environ['COVERAGE_DIR'],
