#296 ClientConnectorSSLError and attachment filenames bugs fix (#297)

* #296 ClientConnectorSSLError bug fix.
Replaced client_auth purpose with server_auth in ssl context creation in order to authenticate web servers. This fix the ssl context issue with Python 3.10.
For the same occasion, we updated rest.py generated code to use a DataForm that does not encode attachment files. aioHttp dataForm object always encodes attachments filenames in utf-8 by default.
