    METRON-1507 Add configuration in development vagrant files to support 
vagrant cac…

    ## Contributor Comments
    This is a Vagrant config change to enable the use of vagrant-cachier to 
reduce build times for the full dev platform. Time saving is heavily network 
dependent, but anecdotally I've found it saves me around 10 mins per provision 
of vagrant development environment. YMMV.
    
    To test:
    
    1. Install vagrant-cachier, and spin up centos and ubuntu vagrant 
development platforms.
    2. Verify that packages are populated into your local (the client running 
vagrant) ~/.vagrant/cache directories.
    3. vagrant destroy your development environments
    4. spin up vagrant environments again, packages should be pulled from the 
cache instead of the network at this point.
    5. spin up a vagrant environment on a machine that does not have cachier 
installed and ensure that the dev platform still builds
    
    Note that the vagrant-cachier plugin is not required, nor shipped, bundled 
or in any way distributed by this change. It does have a compatible license 
(MIT) but it is outside of the Metron project scope to install this, so there 
is no need to update license or dependency documentation.
