API for getting paths exposed for an environment

[whitlockjc]

We need an API that will return the unique list of paths for all deployed applications within that environment. This would be a GET operation on /environments/{org}:{env}/paths and it should return a structure like this:

{
  "paths": [
    "/foo",
    "/bar"
  ]
}

Hold off on this, proposed design might render this unnecessary.

I had a slightly different idea for this. I imagined that if there is an environment whose hostName is nike-test.apigee.net, then we would support a runtime GET on https://nike-test.apigee.net/__paths__.This would be implemented by having the router generate a file containing a list of paths at the time it generates the nginx config. It would also generate a 'location' for /__paths__ that returns this file. If we wanted to have https://api.enterprise.apigee.com/v1/o/nike/environments/test/hostedTargetPaths return the same thing, that could be arranged by just forwarding the request. I don't see a motivation to have a enrober URL for this.

@whitlockjc Is this still important? We now store hosts as the environment level but this could be implemented by getting all deployments and parsing their paths annotations.
