Under clusterwide-file-manifest we should have directory tree of the form

dir - K-Y-Z-M 
 K-Y-Z-M/clusterwide-manifest.nmd5

These are the clusterwide manifests - i.e manifests that are produced by comparing the md5s of different nodes from the same cluster,
and producing 2 lists for each of those clusters:

List 1 (matches):
md5sum:/file/path

List 2 (diffs):
md5sum:/file/path

Where List 1 is a list of all files that have the same path, and have the same path and md5sum across the cluster
While list 2 is a list of the inverse of the above.

# Stages

## Stage 1 - Md5:filepath
 - Param 1 - base path (i.e `stage1.sh /` - would produce md5sum for everything under root)
 - Produces a file containing the md5:file on a given system
 - Excludes directories known to contain node-specific directories

## Stage 2 - Base manifest producer -
 Takes in files produced from Stage 1 across a cluster and produces an output base-manifest

## Stage 3 - Compares a stage 1 output against a known stage 2 manifest
