Wrong annotation prefix for LB/ingress hostname

[Vincent Behar]

Environment:

• Kubernetes distribution (e.g. AKS, ACS Engine, GKE, EKS, etc.):
• Kubernetes version (use kubectl version):
• Osiris version (specify by SHA or semver): 0.0.1-2018.12.17.14.39.01-f3f1817
• Install method (specify exact helm install command used):

What happened?

• tried the basic example from the README, didn't work (got a 404) because "request_handling.go:25] No deployment found for host xxx.yyy"
• tried using the osiris.deislabs.io/loadBalancerHostname found in the hello-osiris example, and then the osiris.deislabs.io/ingressHostname, but it didn't worked

What you expected to happen?

• making a request would scale up the deployment, and I would get a 200 response

How to reproduce it (as minimally and precisely as possible):

Anything else that we need to know?

• I made it work by looking at the code, and found that the annotation prefix should be osiris.io - see https://github.com/deislabs/osiris/blob/master/pkg/deployments/activator/index.go
