[Bug] The "cli" feature of the arrow-flight package inadvertently affects TLS

[niebayes]

Removing the "cli" feature will make client not able to retrieve system certificates during a TLS handshake.
I am still investigating the root cause but I suspect it's caused by the indirect tonic/tls-webpki-roots feature the "cli" feature linked to.

I think this is intentional and not a bug, the CLI needs to support TLS, but we don't want this by default
