Add ability to pass Capabilities.APIVersions to template and lint

[mattfarina]

When using the template and lint commands the Capabilities.APIVersions is an empty set because it uses defaults which are currently an empty set. Might be good to provide a set or provide the capability to pass in a set.

Note, lint doesn't let you pass in the version of k8s either. That may also be useful.

I've recently discovered the new helm template command (wooo!)

I've used it to automatically generate some 'default' deployment manifests for cert-manager for users that wish to not use Helm. I've also created a verify script, to ensure these manifests are up to date during our CI process.

We use Capabilities to determine whether to use CRDs or TPRs. We could soon remove that check however, but in the meantime it'd be great if I could do something to make this return true:

{{- if .Capabilities.APIVersions.Has "apiextensions.k8s.io/v1beta1" -}}

@thomastaylor312 this issue also mentions lint. The PR only addressed template

[genofire]

Yes linting is still not solved (but needed)

[avneesh91]

Is there an alternative for this or making link bypass this?
