Looks to be the same root cause as bug 1900075

[xiaokunfeng (kele1997)]

when I install run `sudo microstack init --control --debug`, and try to enable filebeat, I got the errors as below:

2021-04-28 08:57:55,164 - microstack_init - DEBUG - error: error running snapctl: unknown service: "microstack.microstack.filebeat"

Traceback (most recent call last):
....
....

So as we can see, the real error is `unkown service microstack.microstack.filebeat`, the **microstack** appears twice.

Maybe the solution is :

modify file `lib/python3.8/site-packages/init/questions/__init__.py`, modify class `Filebeat`, `Telegraf`,`Nrpe` like this:

```python3
class Filebeat(SimpleServiceQuestion):
    _type = 'boolean'
    _question = 'Would you like to enable Filebeat?'
    config_key = 'config.services.extra.filebeat'
    interactive = True

    @property
    def services(self):
        return [
- '{SNAP_INSTANCE_NAME}.filebeat'.format(**_env)
+ 'filebeat'.format(**_env)
        ]
```

just remove `{SNAP_INSTANCE_NAME}`,and then works
