Description of problem:

Customer has an issue wherein when multiple users fail to  launch their workspaces with `ImagePullBackOff` error which is caused by image registry throttling, when multiple requests are received for pulling `registry.redhat.io/devspaces/code-rhel8`

Since `che-code-injector` container has imagePullPolicy set to Always. Changing it to be set  by default to `IfNotPresent`, should help prevent the issue.
