exchange: expose bundle2 capabilities on pulloperation

This adds a cache and makes accessing the capabilities slightly simpler,
as you don't need to directly go through the bundle2 module. This will
also help prevent a function-level import in streamclone.py.

This patch arguably isn't necessary. But I think it makes things
slightly nicer.

import os

if os.environ.get('COVERAGE_PROCESS_START'):
    try:
        import coverage
        import random

        # uuid is better, but not available in Python 2.4.
        covpath = os.path.join(os.environ['COVERAGE_DIR'],
                               'cov.%s' % random.randrange(0, 1000000000000))
        cov = coverage.coverage(data_file=covpath, auto_data=True)
        cov._warn_no_data = False
        cov._warn_unimported_source = False
        cov.start()
    except ImportError:
        pass
