in an air gapped environment the machine will not be able to check sha checksums or information
around the binary so we should ignore the tasks in that scenario

airgap installs allow users to deploy k3s in a situation where the server is not internet connected
and therefore unable to download anything externally
For some weird reason, string booleans were set on `k3s_control_node` and `k3s_primary_control_node`, making their behavior non-obvious (for python `bool("false") == True`).
This fixes that problem, and BTW restores the ability to create clusters, which got lost with this bug.
After running the role against a cluster, see:
```sh
❯ ansible -i inventories/testing.yaml k8s_node -m command -ba 'kubectl get node'
vm0 | CHANGED | rc=0 >>
NAME STATUS ROLES AGE VERSION
vm0 Ready control-plane,etcd,master 9m19s v1.21.2+k3s1
vm2 | CHANGED | rc=0 >>
NAME STATUS ROLES AGE VERSION
vm2 Ready control-plane,etcd,master 9m22s v1.21.2+k3s1
vm1 | CHANGED | rc=0 >>
NAME STATUS ROLES AGE VERSION
vm1 Ready control-plane,etcd,master 9m22s v1.21.2+k3s1
```
Now, after the patch:
```sh
❯ ansible -i inventories/testing.yaml k8s_node -m command -ba 'kubectl get node'
vm0 | CHANGED | rc=0 >>

vm0 Ready control-plane,etcd,master 2m2s v1.21.2+k3s1

Otherwise, when completely uninstalling the etcd-enabled cluster, it fails with:
```

If you run the role on an ansible configured with that setting, it will fail with:
