Move admin to separate package

[derekisbusy]

Do you want to move the admin controller to a separate package?

There are a couple of advantages to this:

• admin controls can be left uninstalled and possibly moved to another server and use API controls. This way you could have one server admin other servers using single install of admin package and an API. Also there wouldn't be any admin controls that a person could login to using brute force.
• we can attach the admin package as a sub module so it can be defined in backend only for advanced app layouts.

So if you are using the base app you would define the admin in your config as a module or sub module.

'modules' => [
    'user' => [
        'class' => 'comyii\user\Module',
        'modules' => [
            'admin' => [
                'class' => 'comyii\admin\Module',
            ]
        ]
    ]
]

And in advanced apps it would only be defined in backend configs.

It is a good enhancement - but probably this can be taken up at the end or a bit later once we know what all functionality can be taken into admin.
