Usage: nomad quota inspect [options] <quota>
Inspect is used to view raw information about a particular quota.
If ACLs are enabled, this command requires a token with the 'quota:read'
capability and access to any namespaces that the quota is applied to.

-json
Output the latest quota information in a JSON format.
-t
Format and display quota information using a Go template.
