Swagger Key

```
- [x ] bug report -> please search issues before submitting
- [ x] feature request
- [ ] documentation issue or request
- [ ] regression (a behavior that used to work and stopped in a new release)
```

I have tried multiple approaches to specify a key on swagger page in order to "Try It"
- using just generated Bearer Token
- Malirezai posts here https://github.com/malirezai/WorkbenchAzureFunctionAPI and here https://medium.com/@malirezaie/how-to-enable-programmatic-interaction-with-azure-blockchain-workbench-apis-56c0d95c79c0

Nothing helps.

Please, help.
