Support user provided annotations about voyager HOT 2 CLOSED

I also wonder, if we should create a new TPR type to avoid the restrictions on key in configmaps. For example, configmaps do not allow / in their keys. That is why I proposed the json style format. But if we use our own TPR, we can define the annotation maps directly without an extra json format.

from voyager.

This feature was implemented in #105 via ingress annotation.

ingress.appscode.com/annotations.service and ingress.appscode.com/annotations.pod can be added in Ingress annotations. The values for those are json encoded annotation data, that will be applied into service and pods' annotations respectively.

Example:

ingress.appscode.com/annotations.service: '{"foo": "bar"}'

from voyager.
