Add slack channel annotation to all namespaces

[digitalronin]

We ask for a slack channel for any new namespaces, and then add it as an annotation.

But, most of the existing namespaces don't have that annotation, which means it can be hard to track down responsible people in the event of a problem.

Find out what slack channel is appropriate for each of the namespaces in the cluster, and add the relevant annotations via the definitions in the environments repository.

[digitalronin]

FYI, to list all the namespace definitions that don't specify a slack channel:

for f in namespaces/live-1.cloud-platform.service.justice.gov.uk/*/00-namespace.yaml; do \
  grep -q slack $f || echo $f; \
done

I don't think this ticket is done yet. According to

 for f in namespaces/live-1.cloud-platform.service.justice.gov.uk/*/00-namespace.yaml; do   grep -q slack $f || echo $f; done | sed 's/.*gov.uk.//' | sed 's/.00-namespace.*//'

...we still have the following namespaces with no slack annotations:

Thanks @digitalronin - There are bunch of namespaces here based on 'user' name. Do we still want to chase them up or discard these ones ?
