Review comment:
The reason for the TopologyService method taking an InputStream (rather than
a File) is that there is not a File available in every case. In one case, it is
being used to parse a generated String. There could be two signatures, but I
think the InputStream signature supports the two existing cases well enough.
The streams must be closed though.

> Trigger discovery for descriptors at gateway start time

> Key: KNOX-2301
> URL: https://issues.apache.org/jira/browse/KNOX-2301
> Project: Apache Knox
> Issue Type: Improvement
> Components: Server
> Affects Versions: 1.4.0
> Reporter: Philip Zampino
> Assignee: Philip Zampino
> Priority: Major
> Time Spent: 1h
> Remaining Estimate: 0h
>
> Discovery and topology generation is triggered only by changes to provider
> configuration or descriptor files on disk. Knox should also perform discovery
> for all existing descriptors (that include discovery config) when the gateway
> is started.
> This will help ensure that the generated topologies are accurate reflections
> of the proxied services' configurations.
