DeprecationWarning: Inheritance class AuthorizedSession from ClientSession is discouraged

[parthea]

See the build log here which contains the warning below.

google/auth/transport/_aiohttp_requests.py:200
  /tmpfs/src/github/google-auth-library-python/google/auth/transport/_aiohttp_requests.py:200: DeprecationWarning: Inheritance class AuthorizedSession from ClientSession is discouraged
    class AuthorizedSession(aiohttp.ClientSession):

This issue tracks fixing the underlying issue so that the warning is not emitted.

It seems that it may require different approach than inheritance for AuthorizedSession to borrow ClientSession implementation as one of aiohttp maintainers mentioned aio-libs/aiohttp#3185 (comment) .

Transferring to google-cloud-python as the code for google-auth-library-python will be migrated there in 1-3 weeks.
