Merge pull request #68 from strongloop/feature/refactor-usage

run: refactor usage into a text file
run: directly support statsd backends

For new metrics URL formats, start a statsd child process, and use it to
deliver metrics to (at this moment) splunk, console, graphite, and
syslog.
FIX-BEFORE-MERGE: Add strong-statsd as a dependency
Expose worker log transformer/wrapper via config
Use --log mechanism for statsd process
fixup! logger not present when not clustered
run: exit if metrics URL is invalid
fixup! metrics validation, get both arg forms
fixup! statsd child logging, don't assume server has a child
fixup! report correct scope on startup
