This triggers when we update or overwrite variants, and will include the
previous variants and the new variants.

* task: Ban changes to variants through feature
After adding the new `/variants` endpoint for features we now have a way
to access control adding/modifying variants, so the /:featureName
endpoint should no longer allow editing/adding variants.
This removes variants as a known field from the featureMetadata schema
and tells joi to stripUnknown, thus making sure we never include
variants in the initial creation or future update calls.
For the old features v1 API we allow it to declare that it has already
validated the data coming with its own schema, so we should use the data
we get from it. Thus keeping the old v1 functionality intact

Add a new .../:feature/variants API
This adds
- `GET /api/admin/projects/:projectId/features/:featureName/variants` which returns
```json
{ version: '1', variants: IVariant[] }
```
- `PATCH /api/admin/projects/:projectId/features/:featureName/variants` which accepts a json patch set and updates the feature's variants field and then returns
```json
{ version: '1', variants: IVariant[] }
```
- `PUT /api/admin/projects/:projectId/features/:featureName/variants`
which accepts a IVariant[] and overwrites the current variants list for the feature defined in :featureName and returns
```json
{ version: '1', variants: IVariant[] }
- This also makes sure the total weight of all variants is == 1000
- Validates that there is at least 1 'variable' variant if there are variants
- Validates that 'fix' variants total weight can't exceed 1000
- Adds tests for all these invariants.
