Disable hystrix metrics publishing for login module

[jewzaam]

We are having issues with hystrix metrics published to graphite having a prefix that is just crazy. For example, if we have lightblue.whatever as a root prefix, we'll see metrics published with blue.whatever, tblue.whatever, and so forth at the root level AND at various lower levels. It's nuts!

So, we're trying things. This is one of the last ditch things to try. The though is to keep removing variables. We have POC apps running the code from https://github.com/jewzaam/hystrixexample working just fine. Our deployment though has the login module and rest application in two war's deployed on the same host and we think maybe there's something going on there.

I did find the hystrix servo metrics publisher singleton initialization was a bit weak and put Netflix/Hystrix#516 to fix it. Don't think it would matter for this issue though.

This should be closed with #72 ?
