Problems with dots "." in keys

[kifj]

I'm using the RPM packages for graphite-api (v1.1.3) and python-whisper (0.9.15) and python-carbon (0.9.15) on Fedora 24, and I've encountered problems reading some stats gathered by the plugin.

The problems seems to be related with using "." in some keys, as in "localhost/docker-elasticsearch01/cpu.percpu.usage-cpu0". Graphite has some conventions about slashes and dots as folders, and mixing them does not seem to work in the versions I am using.

Replacing "." by "_" in all in metric names in dockerplugin.py fixes the problem
