Annotation prefix is not removed

[ivanayov]

This is the function configuration:

provider:
  name: faas
  gateway: http://127.0.0.1:8080

functions:
  kafka-test:
    lang: python
    handler: ./kafka-test
    image: kafka-test
    annotations:
      topic: faas-request
    basic_auth: false

curl -X GET http://127.0.0.1:8080/system/function/kafka-test should return

{  
   "name":"kafka-test",
   "image":"kafka-test:latest",
   "invocationCount":0,
   "replicas":1,
   "envProcess":"python index.py",
   "availableReplicas":1,
   "labels":{  
      "com.openfaas.function":"kafka-test",
      "com.openfaas.uid":"92309200",
      "function":"true"
   },
   "annotations":{  
      "topic":"faas-request"
   }
}

but instead the annotations are prefixed:

 "annotations":{  
      "com.openfaas.annotations.topic":"faas-request"
   }

Possible Solution

The bug is on reader.go#L95.
The prefix is not removed.

Context

Found while testing pull #6
Follows #28

Some integration tests are good to have.
