Rancher AWS: Resource `module.rancher_common.helm_release.cert_manager` runs into 5m timeout during destroy

[wombelix]

Issue:
Helm uninstall of cert-manager runs into 5m timeout during destroy.

Reason:
As long Rancher Quickstart uses an (outdated) cert-manager version below 1.15.0, the problem doesn't occur:

https://cert-manager.io/docs/installation/helm/#uninstalling-with-helm

cert-manager versions prior to v1.15.0 do not keep the CustomResourceDefinition on uninstall and will remove all Issuers,ClusterIssuers,Certificates,CertificateRequests,Orders and Challenges resources from the cluster. Make sure to back up your cert-manager resources before uninstalling cert-manager if you are using a version prior to v1.15.0. Or upgrade to v1.15.0 before uninstalling.

Running Helm manually without --wait, uninstall works but provides this additional output:

These resources were kept due to the resource policy:
[CustomResourceDefinition] certificaterequests.cert-manager.io
[CustomResourceDefinition] certificates.cert-manager.io
[CustomResourceDefinition] challenges.acme.cert-manager.io
[CustomResourceDefinition] clusterissuers.cert-manager.io
[CustomResourceDefinition] issuers.cert-manager.io
[CustomResourceDefinition] orders.acme.cert-manager.io

When using --wait / wait = true, Helm will wait for the CRDs to be gone, which will never happen.
Easiest fix is to use wait = false, Rancher depends on cert-manager but doesn't need all resources up and running during installation.

Fixing this Issue will unblock the cert-manager version bump in #240 too.
