Minimum viable Elasticsearch Graphite

Inspired by dlutzy's excellent mvredisgraphite here is mveg.

Hopefully pretty simple to use, make sure mveg.py and mveg.sh are in the same folder and set the following environment variables:

• ENVIRONMENT - basically a prefix
• APP_NAME - varies the application name used
• HOSTNAME - the name of the host being queries (defaults to the output of hostname)
• ES_HOST - the host on which Elasticsearch is running
• ES_PORT - the port on which Elasticsearch is running
• CARBON_HOST - the host on which Carbon is running
• CARBON_PORT - the port on which Carbon is receiving metrics

Then run mveg.sh from wherever you've put it. It'll gather the metrics from Elasticsearch and fire them over to Carbon.

This will start creating metrics with a prefix of $ENVIRONMENT.$APP_NAME.$HOSTNAME. It's a bit specific to my use-case, any customisations are more than welcome.
