fix parsing of grafana feature flags that're enabled via the feature_…

…toggles.enabled syntax (#2477)

# What this PR does

Grafana provides two methods for enabling feature flags:
- `feature_toggles.enabled`
- `feature_toggles.<name_of_feature_flag>`

For example, to enable `accessControlOnCall` you could either do:
```json
{
  "feature_toggles": {
    "enabled": "accessControlOnCall,someOtherCoolFeatureFlag"
  }
}
```

or:
```json
{
  "feature_toggles": {
    "accessControlOnCall": true,
    "someOtherCoolFeatureFlag": true
  }
}
```

In method 1, if they're multiple feature flags present, they are _comma
separated, not space separated_. This PR fixes this parsing issue.
