[kkaempf]

SURE-9228

Issue description:

When adding a specific toleration to values.tolerations, the fleet-cleanup-clusterregitrations pod does not use them. See here for the code and the image attached for an example.

Business impact:

The pod cannot run in a cluster where all nodes are tainted.

Repro steps:

• Create a new cluster using k3s/rke2
• Taint the node
• Install rancher

-- see JIRA --

Actual behavior:

Pod does not run in a cluster with all nodes tainted and chart installation fails.

Expected behavior:

Pod uses the tolerations from values.tolerations and can run in a tainted node.
