[`feature bug 1840235 <https://bugs.launchpad.net/keystoneauth/+bug/1840235>`_]
Adds ``connect_retries`` to Session.__init__(), that can then be used
by projects when creating session objects, to set the required number of
retries for new connection requests. This would specifically help avoid
a scalability issue that results in number of ConnectTimeout errors when
doing endpoint discovery and fetching roles using an auth plugin under
heavy load. This still allows for it to be overridden per service with
the adapter interface.
