This update contains several changes
- Used a more recent commit of envoy specifically the one right before
  they broke it until the envoy team fixes the issue.
- Exposed envoy's admin interfacet to enable the gathering of NBI
  activity stats from the cluster.
- Removed some unncessary filters from Envoy to reduce the size of the
  config file and make it easier to understand.
- Removed the envoy directory and the mount thereof because everything
  now comes packaged in the containter.
- Fixed a bug int the cluster VM Vagrantfile that was causing kernel
  panics on some architectures.
- Added a log collection script to facilitate problem reporting.
- Removed the nginx directory from the install since nginx isn't being
  used in production.
