skyprovider
Advertises a service to skydns via skyapi.
Whatever name
you use choose will have services.[root]
appended to it. If
your etcd root was example
and you provide'd with name auth-api
then the
SRV record would be under auth-api.services.example

Once providing has started the library will automatically ping skyapi every 15 seconds. If disconnected it will automatically try reconnecting every 3 seconds.
