The logs suggest that the test failure is because of flaky CI, so I am going to recheck it. |

hardenedSecurityContext, setting its type to SeccompProfileTypeRuntimeDefault so

This is kind of odd but ok. We should probably add RestrictiveReadOnlySecurityContext() in lib-common to get rid of this in a followup.

Description:
Applies a hardened SecurityContext to the OpenstackProvisionServer containers. This SecurityContext makes sure that it runs as non root, does not allow privilege escalation, read only root file system, drops all capabilities. Also created emptyDir scratch volumes for the paths that still need to be writable.
The provision server container uses hostnetwork SCC which disallows using SeccompProfile.
