Convert all helm-template instructions to helm-install (#828)

Browse Source 
* Adjust command to install cert-manager

The directory `cert-manager` is not created when using `helm install`
instead of `helm template --output-dir .`.

Also, the CRDs are downloaded in the current directory, so adjust the
commands as well.

* Convert helm template to helm upgrade/install

Since we're using Helm hooks, we cannot use `helm template`, otherwise
things will break. The commands are updated to use `helm install` and
`helm upgrade`.

### Rendering the Helm Chart for Air Gap Installations
### Enabling Features for Air Gap Installs
For an air gap installation of Rancher, you need to add a Helm chart repository and render a Helm template before installing Rancher with Helm. For details, refer to the [air gap installation documentation.](../getting-started/installation-and-upgrade/other-installation-methods/air-gapped-helm-cli-install/install-rancher-ha.md)
To perform an [air gap installation of Rancher](../getting-started/installation-and-upgrade/other-installation-methods/air-gapped-helm-cli-install/install-rancher-ha.md), add a Helm chart repository and download a Helm chart, then install Rancher with Helm.
Here is an example of a command for passing in the feature flag names when rendering the Helm template. In the below example, two features are enabled by passing the feature flag names in a comma separated list.
The Helm command is as follows:
When you install the Helm chart, you should pass in feature flag names in a comma separated list, as in the following example:
```
helm template rancher ./rancher-<VERSION>.tgz --output-dir . \
--no-hooks \ # prevent files for Helm hooks from being generated
helm install rancher ./rancher-<VERSION>.tgz \
--namespace cattle-system \
--set hostname=<RANCHER.YOURDOMAIN.COM> \
--set rancherImage=<REGISTRY.YOURDOMAIN.COM:PORT>/rancher/rancher \
