+1 for the change. This would fix dependency conflicts between httpclient
4.2.5 and 4.3.5.
I think the question is whether we should publish a separate shaded
artifact (like we did for ning-ahc) for the shaded httpclient 4.3.5, or
just shading it internally in apex-engine. The former allows application
and operator developers to use the shaded artifact and the latter hides it
completely.
