Rename "cluster" config entry to "mesh" (#10127)

This config entry is being renamed primarily because in k8s the name
cluster could be confusing given that the config entry applies across
federated datacenters.

Additionally, this config entry will only apply to Consul as a service
mesh, so the more generic "cluster" name is not needed.
