If ssl=True is passed as a keyword arg (or ssl=true in the URI)
but no value for ssl_cert_reqs or ssl_ca_certs has been provided,
assume ssl.CERT_REQUIRED for cert_reqs and attempt to load
system provided CA certificates. Raise ConfigurationError if
the necessary SSLContext methods don't exist.
The min_wire_version and max_wire_version attributes have
always been racy when connected to a mixed version replica set
or any sharded cluster. When connected to a mongos all you know
is the wire version of that mongos, not the shards behind it.
With mongos load balancing this problem is even worse, since
each operation could possibly be executed on a different mongo
version during an upgrade.

As with the Python functions, the C implementations of _do_batched_insert and
_do_batched_write command must now take a SocketInfo, not a MongoClient, to
ensure they send the OP_INSERT or write command over the same socket used to
determine the server's wire protocol version.
