Ability to Override Existing Deployment

[kahboom]

Current Situation

If there is a deployment with the same name as the current integration on the Visualization, you will get an error from the backend, but it may still not be clear to the user. We are slightly limited in the information we get back for deployments.

Solution

We should be checking if the name is the same as an existing deployment, and ask them if they want for it to be overridden. We would then delete the integration and recreate it with the new settings and steps.
