Can't bootstrap clusters with Rancher v2.7.5-rc2

[bk201]

We can't bootstrap a cluster when integrating Rancher v2.7.5-rc2.

To reproduce:

• Change local-rke-state secret type: bk201@1aca2c1
• Bump Rancher v2.6.5-rc2 in Harvester: https://github.com/bk201/harvester-installer/commits/bump-rancher-275-rc2
• Start a Harvester cluster.

Analysis

Keep seeing this log in rancher pod:

│ 2023/05/30 09:10:09 [INFO] [planner] rkecluster fleet-local/local: waiting: waiting for at least one control plane, etcd, and worker node to be registered                                │

There is no "machine" object created.

Rancherd bootstrap procedure:

Rancherd creates this resources after deploying Rancher chart and wait for rancher services ready.
