Disable TLS validation

[sempervictus]

We have rportd and rport-pairing running in our private cloud with the client and pairing endpoints exposed on the WAN at their respective ports, but the API only accessible through the private networks within the cloud on another port (for which we use the internal IPs or DNS names served up by Designate). This creates a bit of a problem for rportcli:

$ rportcli client list
FATAL: operation failed with an error: Get "https://internal.host.local:9443/api/v1/clients?fields%5Bclients%5D=id%2Cname%2Ctimezone%2Ctunnels%2Caddress%2Chostname%2Cos_kernel%2Cconnection_state%2Cdisconnected_at&page%5Blimit%5D=50&page%5Boffset%5D=0": x509: certificate is valid for wan.host.tld, not internal.host.local

This is something i run into with Go and Rust quite a bit - produced binaries don't have a --disable-cert-validation type of CLI flag. Any chance there is one, or an environment variable i can set, and i'm just not seeing it in the CLI or the docs?
