Allow TLS verification to be skipped

[Xiol]

Hello,

In production we're using valid TLS certificates only for securing the connection, not validating the client. However in test I'm using self-signed certificates for this. There doesn't appear to be a way to disable the NATS client from attempting to verify the TLS certificate of the server. It would be nice to have this option.

Thanks

Are you signing the certs using a internal CA for test purpose? This is quite easy and then you just tell it the path to the CA?

No, I didn't want to go through the hassle of setting up a CA.

It's the right thing to do though and its really easy.

That said, server does support disabling verify so seems reasonable CLI should too, its a easy PR if you want to else it might take some time.
