Unable to disable `InsecureSkipVerify` in webSocket comm layer

[ale-linux]

The implementation defines the TLS configuration for all clients in newClient here. The caCertPool argument is however always nil (see call here). As a result, the client will never actually verify whether the server presents a valid certificate.

Now the TLS configuration can be easily made configurable using core.yaml. Modify the NewConfig method in:

https://github.com/hyperledger-labs/fabric-smart-client/blob/main/platform/view/services/comm/host/rest/config.go

And return the appropriate TLS configs for the client and the server
