Automatically set offline_kube_version for charts with CRDs used

[r3nic1e]

Imagine we try to install kube-prometheus-stack. It has some CRDs defined and also some resources that use it.
Since we try to run dry-run install to get manifests, it fails (no CRDs are deployed yet).

Right now there is one workaround for this: offline_kube_version. It is required only during first install.

The proposal is:

• Either automatically enable offline_kube_version if we get the error and retry
• Or discover CRDs in the release and try to hack kube mapping to include those CRDs
