Clean up numerous classnames

All commands define their own classname even though it is not visible to other code.

example from `commands/runtime/action/create.js`
```
class ActionCreate extends RuntimeBaseCommand {
}
...
module.exports = ActionCreate
```

Ideally these should all just be `Command` or something generic, and they should all be the same, much like the way the tests all specify the commands they are testing with : `const TheCommand = require('..`

Start with commands/runtime/action/create.js and compare the command class declarations across the commands directory. Review the tests' pattern of assigning a generic required command to a local name, then identify all command classnames that are private to their modules. Done means the command classes use a consistent generic name without changing command behavior.
