please implement calicoctl version --client

[den-is]

Expected Behavior

calicoctl version --client should not query Cluster API and return calicoctl version only.

I have ansible roles that install tools and check their versions to determine on action (install/update or skip). Helm, kubectl, cilium - allows to query cli binary version only (offline) without communicating to the cluster.

Current Behavior

calicoctl version | head -1 | grep -E -o "v[0-9]+\.[0-9]+\.[0-9]+" This command always tries to communicate to the server and returns exit code 1 when server is not available.
And cluster is not available in many cases, either I try to install calicoctl before cluster setup, or installing calicoctl on some remote workstation without immediate access to the cluster.

Possible Solution

helm version --template='{{ '{{' }}.Version{{ '}}' }}' kubectl version --client -o json | grep -i gitversion | grep -E -o "v[0-9]+\.[0-9]+\.[0-9]+" (no jq) cilium version --client | head -1 | grep -E -o "v[0-9]+\.[0-9]+\.[0-9]+"

Looks like it will return exit code 0 if not configured to talk to a server, but if configured (e.g., with a kubeconfig) it will return an error.

Seems like a reasonable enhancement request to make that configurable though.
