Subject: [PATCH] node_status: Add CSI Summary info

This commit introduces two new fields to the basic output of `nomad
node status <node-id>`.

1) "CSI Controllers", which displays the names of registered controller
plugins.

2) "CSI Drivers", which displays the names of registered CSI Node
plugins.

However, it does not implement support for verbose output, such as
including health status or other fingerprinted data.
