RegisterInstrumentation option can not be changed in yaml, refer to https://github.com/weaveworks/common/blob/master/server/server.go#L33.

But in https://github.com/weaveworks/common/blob/master/server/server.go#L158-L160, still do check.

Better to expose this setting to yaml setting.
