ClusterHost is an incorrect parameter / term for url creation

/kind feature

Which functionality do you think we should add?

--clusterHost should be --host for odo url create.

Why is this needed?

ClusterHost parameter for url creation is an incorrect parameter term.

The term Cluster Host in kubectl and oc is confusing because Cluster Host actually means Kubernetes / OpenShift "host".

It is confusing because we are specifying a domain name for url creation.. ex: odo url create --clusterHost example.domain.com

We should be using the correct term which would actually be host, which is exactly what OpenShift uses in the yaml creation for Route.

For example, the current code that is implemented looks like this:

				Host: ingressParam.IngressDomain,

The host we want user to specify is the cluster host, not the entire ingress domain.
If the ingress domain we want is example.domain.com, then the command should be
odo url create example --clusterHost domain.com
(ingressDomain = urlName.clusterHost)

If we don't want camel case in the command, the parameter can be simplified as host

"Cluster Host" is a different definition as "host" or ingress. "Cluster Host" is also not used at all within Kubernetes / OpenShift YAML.

If you want to define an ingress domain, it should just be host similar to Kubernetes / OpenShift YAML definitions.

I agree to switching it to just --host.
