Upgraded Chaos dependency to latest release (0.5.2).  Added an override for the resource cache control header value to burst browser caches for static assets.
Merge pull request #135 from mesosphere/wip-cache-burst

Burst Browser Cache for Static Assets
Append "v=1" to bust cache for next JS request

Since this will go out with the release of Marathon that serves
"must-validate" cache headers, this version string only needs to be
updated once.

This pairs with commit 9cbf3a916930fc30392fedb8e6ab8851eab58c83, which
responds with "Cache-Control: max-age=0, must-revalidate".
