Bug: Kubeslice runs with privileged permissions, we need a minimal set of permissions.

### 📜 Description

In openshift environment kubeslice cannot run as with privileged permissions, there needs to be minimal set of permissions to run kubeslice in openshift.

We can achieve this with a security context with a minimal set of permissions instead of running kubeslice with full privileged permissions.

This change will have to be applied in a number of KubeSlice components not just worker-operator.

### 👟 Reproduction steps

install kubeslice in openshift

### 👍 Expected behavior

It should run in openshift without privileged permissions out of the box.

### 👎 Actual Behavior

Fails to run kubeslice on openshift

### 🐚 Relevant log output

```shell
