In order to use CAAPF for deploying calico CNI as a helm chart we need to replicate the behavior for chart templating:

• https://github.com/rancher/turtles/pull/448/files#diff-6977749061d5021a72c12350e8c159bbb9b257dbacba21a1a727ed8029916721R24

There is an issue for that: rancher-sandbox/cluster-api-addon-provider-fleet#32 which needs to be implemented.

I don't remember us having discussion on why using CRS should be replaced by CAAPF?
I would appreciate if we could discuss the benefits over the current CNI installation solution and why can't we have both tested in e2e tests, since CRS seem to be still relevant upstream.

@furkatgofurov7 This change only adds CSI provisioning tests. CRS are tested upstream, we don’t need to duplicate this if there is an alternative. The CAAPF provides an alternative method, which does not yet have test coverage. This change adds it within turtles.

Prior approach to CAAPF is usage of CAAPH, in #448 but since Fleet is installed in every rancher cluster, we can use it to perform same functionality as CAAPH.

Alright that makes sense, by PR description I had the feeling that CRS are not relevant at all in turtles and we completely drop its usage. Using CAAPF instead of CAAPH is a good improvement towards wider adoption of CAAPF.
