Only init statsd if STATSD_HOST in config
Added some documentation
Added timers on cloudamber
Added statsd on LDB
Added metric to Solr request
Init statsd or it will break when it is not configured
Fixed unit tests problems introduced due to statsd not being init
Added a LocalProxy for importing a configured statsd
Reverted the import trickery

This was hiding an underlying problem with having a statsd singleton
Tests would pass when executed after the singleton had been initialised
but not when ran individually.
Don't init statsd with the app, init as required.
Replaced the usage of statsd.timer as a decorator with a contextmanager
Move from decorator to contextmanager
Timing all views from moxie.core.views
Updated documentation
