Add Labels and Annotation at Rule creation

[fglaeser]

For what I saw, the only way to add label and annotations to one rule is the following:

1. Create the Rule.
2. Edit the rule, add labels or annotation
3. Save the rule.

It will be good to be able to add labels and annotation at rule creation.

It's a good point. The existing flow is partly a result of the underlying Django model leaking through a bit, but it would not be too difficult to add.
