refactor: support outputTemplate flags for non-request based commands

[reubenmiller]

Previously commands like non-request based commands like c8y version, c8y show util etc. didn't support the global --outputTemplate flag. Now the majority of commands support output templates for a more consistent experience.

There might be some notable exceptions in the future, but in general you should be able to use --outputTemplate by default everywhere.

Example: c8y version

% c8y version --outputTemplate "{custom:{shape: output}}" | jq
{
  "custom": {
    "shape": {
      "branch": "refactor-generic-worker",
      "version": "2.40.0-SNAPSHOT-d52844df"
    }
  }
}

Example: c8y extensions list

% c8y extensions list --outputTemplate "{some:{other:output}}" | head -1 | jq
{
  "some": {
    "other": {
      "isBinary": false,
      "isLocal": false,
      "name": "defaults",
      "path": "/Users/reubenmiller/.cumulocity/extensions/c8y-defaults",
      "pinned": false,
      "repo": "reubenmiller/c8y-defaults",
      "version": "c4c17a36"
    }
  }
}
