enable CORS

[enriquezrene]

When the UI is trying to interact with the API, the console is showing the following error:

Access to XMLHttpRequest at 'http://timetracker-api.azurewebsites.net/activities' from origin 'http://localhost:4200' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

We need to enable CORS so these requests can be executed with no problems during local development and also from the app deployed in the cloud https://time-tracker-ui.azurewebsites.net/

Acceptance Criteria

• Requests executed from localhost and https://time-tracker-ui.azurewebsites.net/ can be executed with no problems
