---------------------------------

Some of the information in this patch needs to be transferred up to BIGTOP-1365, i think....

if somone gets a chance, please clarify for me why the configuration files go in "config/" instead of just {{--confdir}} . 

Seen some other folks who had some struggles getting the right  config option from googling around http://apachebigtop.pbworks.com/w/file/fetch/52304359/Puppet.pdf getting this working.

> Previously, bigtop-deploy puppet could only be configured by editing puppet manifests, or through a small number of environment variables that set facter facts.  I've rewritten cluster.pp to use extlookup to read most configuration options from a site-specific CSV file with sane defaults for most options (only hadoop_head_node and bigtop_yumrepo_uri are required to be set).  These changes should make it easier to automate deploying multiple clusters with different configurations from the same manifests.
> As written, the CSV files must live in $confdir/config/, where $confdir is the puppet config directory.  This means that if you are manually calling 'puppet agent' on these manifests (rather than serving them from a puppet master), you are now required to specify --confdir in addition to --modulepath.
> At some point in the future, may be worth moving to hiera, as yaml is a lot prettier and more flexible than CSV.  I did this using extlookup so as not to introduce external dependencies (since extlookup is now in puppet core).
