modify key namespacing to be easier to configure

This makes some changes to what the default key namespaces are and how they are
configured. Basically it puts the config under the graphite key and doesn't
need the user to take care of where dots are set.
fix the tests
Make it clearer that sampling is only for counters.
Fix for config.js, use fs.watch instead of fs.watchFile
Increments bad_lines_seen when sampleRate bit does not match regex

This introduces the `graphite.legacyNamespace` boolean flag which can be used
