Add enable_unsafe_legacy_renegotiation param to work around

[markrileybot]

requests.exceptions.SSLError: HTTPSConnectionPool(host='vpn.mycompany.biz', port=443): Max retries exceeded with url: /global-protect/prelogin.esp (Caused by SSLError(SSLError(1, '[SSL: UNSAFE_LEGACY_RENEGOTIATION_DISABLED] unsafe legacy renegotiation disabled (_ssl.c:997)')))

Just fyi... the following approach does not require any code changes:

export OPENSSL_CONF=openssl.cnf
gp-okta.py

Contents of openssl.cnf:

openssl_conf = openssl_init

[openssl_init]
ssl_conf = ssl_sect

[ssl_sect]
system_default = system_default_sect

[system_default_sect]
Options = UnsafeLegacyRenegotiation
