chore: allow overriding the default SSO callback listener for docker integration

[Shaked]

By default argocd creates an SSO callback listener address to localhost (127.0.0.1), which means that within a docker container, the only way to map this address from the host into the port, and allow the callback to work, requires the installation of socat and running socat TCP4-LISTEN:8086,fork TCP4:127.0.0.1:8085 & within the container.

This PR allows using argocd login sso via a docker container by changing the callback listener address. For example:

./dist/argocd login argocd.example.com --sso-listener-address "0.0.0.0" --sso --loglevel debug
WARN[0002] Failed to invoke grpc call. Use flag --grpc-web in grpc calls. To avoid this warning message, use flag --grpc-web.
