Add control-plane toleration to system-upgrade-controller.

[rawlink]

Description

The system upgrade controller manifests only specify a toleration for the deprecated node-role.kubernetes.io/control-plane=true:NoSchedule taint. I run my clusters with the newer node-role.kubernetes.io/control-plane=true:NoSchedule taint but I have to manually patch the system-upgrade-controller manifests for it to run with the newer control-plane taint.

Changes

• Add node-role.kubernetes.io/control-plane toleration to system-upgrade-controller manifests.
• Bump system-upgrade-controller to v0.7.5.

Testing

Tested manifest changes in k3os kubernetes clusters -- system-upgrade-controller runs correctly in clusters with node-role.kubernetes.io/control-plane=true:NoSchedule taint on controller nodes. Also tested v0.7.5 deploys and starts up correctly.

@rawlink thank you for this. Can you also bump SUC to 0.7.5 please?

@dweomer Bumped SUC version to v0.7.5. Everything seems to be running fine in my dev cluster.
