This looks at the PreparedRequest, the user-specified verify value,
and the value of the cert parameter to determine what PoolKey values
to use to select a connection from a given urllib3 Connection Pool.
The SSL related pool key arguments are not consistently set. As of
this writing, use the following to determine what keys may be in that
dictionary:
* If ``verify`` is ``True``, ``"ssl_context"`` will be set and will be the
default Requests SSL Context
* If ``verify`` is ``False``, ``"ssl_context"`` will not be set but
``"cert_reqs"`` will be set
* If ``verify`` is a string, (i.e., it is a user-specified trust bundle)
``"ca_certs"`` will be set if the string is not a directory recognized
by :py:func:`os.path.isdir`, otherwise ``"ca_cert_dir"`` will be
set.
* If ``"cert"`` is specified, ``"cert_file"`` will always be set. If
``"cert"`` is a tuple with a second item, ``"key_file"`` will also
be present
To override these settings, one may subclass this class, call this
method and use the above logic to change parameters as desired. For
example, if one wishes to use a custom :py:class:`ssl.SSLContext` one
must both set ``"ssl_context"`` and based on what else they require,
alter the other keys to ensure the desired behaviour.
