The -x/--exclude option drops matching node and node group attributes
from a dump, restore, or merge, so a backup can leave out dynamic state
such as deployment.state_last_updated or data that should not travel with it.
Patterns use shell-style wildcards, and a bare namespace such as net
excludes every attribute below it. The node "groups" and "id.index"
attributes and the node group "noderange" attribute are always retained
so that a restore can still reconstruct group membership and node index
assignments.
Adds `confluentdbutil showattrib <noderange> <attribute>...` to print the
node attribute.
In contrast to nodeattrib it can shows secrets and crypted values with -u flag.
It's server-side only: reads the config store and master key directly, never over
the API.
It's read-only and works without confluentd running.
