Several commands that inspect objects where the names are user-controlled share a bug where the user cannot inspect the object if it has a name that is an exact prefix of the name of another object (in the same namespace, where applicable). For example, the object "test" can't be inspected if there's an object with the name "testing". Copy existing logic we have for jobs, node pools, etc. to the impacted commands: * `plugin status` * `quota inspect` * `quota status` * `scaling policy info` * `service info` * `volume deregister` * `volume detach` * `volume status` If we get multiple objects for the prefix query, we check if any of them are an exact match and use that object instead of returning an error. Where possible because the prefix query signatures are the same, use a generic function that can be shared across multiple commands.

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.
