CSIT-1416 Remove installation of vpp from containers

Use parent system (Host, Container) installation of VPP. This will save
the internet bandwith by skip installing of prerequisites packages.
It will also skip dpkg install and simplify the process of initializing
VPP inside container.

Previosly initialization of VPP in container takes about 55s. With this
patch it is reduced to 2-3s.

This patch removes the bloated VOLUME creation between container
sidecars (a.k.a nested container) and fixes the hugepage allocation.
