CASMINST-6829 - CSM health checks should detect when Weave has a peer in "sleeve" mode

[spillerc-hpe]

Summary and Scope

If Weave has peers running in "sleeve" mode instead of the fast dataplane (fastdp) mode then pod to pod communication errors can occur resulting in strange behaviour from services running in Kubernetes.

The upgrade procedure has a check for this due to an old issue FN #6636 where the MTU was set incorrectly however the standard CSM health validation tests do not check for this condition.

This PR modifies the goss-weave-health.yaml test to check for this condition.
