Does the output stream need to be closed?

> Add Service Definition Management to Admin API
> ----------------------------------------------
>
> Key: KNOX-2053
> URL: https://issues.apache.org/jira/browse/KNOX-2053
> Project: Apache Knox
> Issue Type: Improvement
> Components: Server
> Reporter: Larry McCay
> Assignee: Sandor Molnar
> Priority: Major
> Fix For: 1.4.0
>
> Time Spent: 40m
> Remaining Estimate: 0h
>
> Currently, the Admin API allows management and access to topologies,
> descriptors, provider config, etc but does not provide access to the Service
> Definitions for the proxied services.
> Let's expand the API the include to include service defs and allow for
> customization through the API. Changes made via the API will typically
> require a restart and touch of an topology file that is referencing the
> change service def. This may require a separate Jira and effort to address.
> In the meantime, we should be able to change, add and delete service
> definitions including both service and rewrite XML files.
