Deploy staging with HTTP to staging.cellmapchallenge.2i2c.cloud

[yuvipanda]

We need to have a staging deployment of the application to be able to test things before taking them to production.
Now that a dummy deploy has happened successfully we need to do one, specific to staging.

Definition of Done

• run kubeclt get svc to get the public IP of the ingress controller
• go to namecheap and add an A record to route all requests to staging.cellmapchallenge.2i2c.cloud to this IP
• create a staging.values.yaml file
• this values file setups ingress.hosts to hold staging.cellmapchallenge.2i2c.cloud domain
