Created iterator to go through basicStats i.e.
[u'diskUsed', u'memUsed', u'diskFetches', u'quotaPercentUsed',
u'opsPerSec', u'dataUsed', u'itemCount']

the metric value is the same as the key. So we are pushing itemCount =
7303 and not item.Count, at the moment
expanded collected statistics from couchbase to include interestingStats
from nodes and quota

using json module by default, if not existing try to use simplejson
modified configuration parameters
exception indentation error
data["nodes"] is an array, modified code to pick the first entry from node
Refactored publishing code for readability. It is possible that "nodes"
may require iteration, at the moment only checking first element of node list
Forgot the stat identifier
