mgr: fix enabling of mgr module on mimic

The data structure has slightly changed on mimic.

Prior to mimic, it used to be:

```
{
    "enabled_modules": [
        "status"
    ],
    "disabled_modules": [
        "balancer",
        "dashboard",
        "influx",
        "localpool",
        "prometheus",
        "restful",
        "selftest",
        "zabbix"
    ]
}
```

From mimic it looks like this:

```
{
    "enabled_modules": [
        "status"
    ],
    "disabled_modules": [
        {
            "name": "balancer",
            "can_run": true,
            "error_string": ""
        },
        {
            "name": "dashboard",
            "can_run": true,
            "error_string": ""
        }
    ]
}
```

This means we can't simply check if `item` is in `item in
_ceph_mgr_modules.disabled_modules`

the idea here is to use filter `map(attribute='name')` to build a list
when deploying mimic.
