Disabling the UID Policy rule was a workaround for #9928. Re-enable
that rule here and add a new test/CI temporary workaround for this
issue. This new test workaround will be removed after fixing #9928.

Change quay.io/prometheus/busybox to quay.io/prometheus/prometheus in
this test. The prometheus image will be helpful for testing the future
fix for #9928 because it specifies user = "nobody".
Also, change:
sh -c "ls -l /"
to:
echo -n "readinessProbe with space characters"
as the test readinessProbe command line. Both include a command line
argument containing space characters, but "sh -c" behaves differently
when using the prometheus container image (causes the readinessProbe
to time out, etc.).

Add tests for genpolicy's handling of container.exec_commands. These
are commands allowed by the policy and originating from these input
K8s YAML fields:
- livenessProbe
- readinessProbe
- startupProbe
- lifecycle.postStart
- lifecycle.preStop

Auto-generate the policy and then simulate attacks from the K8s
control plane by modifying the test yaml files. The policy then
detects and blocks those changes.
These test cases are using K8s Pods. Additional policy failures
are injected during CI using other types of K8s resources - e.g.,
using Jobs and Replication Controllers - from separate PRs.
