no-check-certificate option ( -x)

From F5 support
Known Issue
Server certificate verification may fail with the BIG-IP Edge Client command line for Linux.
Connection Status: logon failed
Server certificate verification failed.

F5 Workaround
To work around this issue, you can disable certificate verification using the -x option to the f5fpc command.
For example:
f5fpc -s -x -t https://apm1.example.com

But seems that the -x option is not recevied by the docker-f5fpc
./f5fpc-vpn.sh client -x -t https://sslvpn-xxx.xxx.it
Please enter your VPN username: xxx
Please enter your VPN password:
Logon denied
Connection Status: logon failed
Server certificate verification failed.

It is possible to add this option?

Sure, it's possible. But I don't know when I will have the time for implementing that. For speeding things up, feel free to submit a pull request.
