Delete all versions from a schema

[fraballi]

Great tool.
I need to create from scrash schemas in unit tests and deleting schemas is a must.
Does your API fully conforms with Confluent's? How can I delete a schema and all its versions?
e.g

Delete version 3 of the schema registered under subject "Kafka-value"

$ curl -X DELETE http://localhost:8081/subjects/Kafka-value/versions/3
  3

Delete all versions of the schema registered under subject "Kafka-value"

$ curl -X DELETE http://localhost:8081/subjects/Kafka-value
  [1, 2, 3, 4, 5]

We strive to keep the API compatible with the Confluent API but we haven't had a chance to implement the delete API yet. See #48 for the tracking issue for deletes. PRs are always welcome ;)
