Changes

Rename Available Commands to Main Commands

Why

If Management Commands and/or Permission Commands groups are present, it is a bit confusing from --help that they are also available.

before:

% databricks permissions --help
Usage:
  databricks permissions [flags]
  databricks permissions [command]

Available Commands
  get                   Get object permissions.
  set                   Set object permissions.
  update                Update object permissions.

Permission Commands
  get-permission-levels Get object permission levels.

after:

% ./cli permissions --help
Usage:
  databricks permissions [flags]
  databricks permissions [command]

Main Commands
  get                   Get object permissions.
  set                   Set object permissions.
  update                Update object permissions.

Permission Commands
  get-permission-levels Get object permission levels.

Flags:
  -h, --help   help for permissions

Tests

This is now a bit inconsistent with how Cobra behaves if there are no groups (it still prints Available Commands: in that case).

We could also do "Available Commands (Main)", "Available Commands (Permissions)", here
