Add mTLS as default HTTPConnect egress configuration for GCP.
We currently have UDS as the configuration with GRPC. Some users are setting up egress to remote konnectivity servers. Cannot use UDS for this configuration. Should have a config setup which validates the mTLS configuration. Fixed lint errors from shell check. Fix volumes to not include pki for ANP in grpc mode.
