This adds a new interface that a provider can implement which enables
async notifications of pod status changes rather than the existing loop
which goes through every pod in k8s and checks the status in the
provider.
In practice this should be significantly more efficient since we are not
constantly listing all pods and then looking up the status in the
provider.
For providers that do not support this interface, the old method is
still used to sync state from the provider.
This commit does not update any of the providers to support this
interface.
* Define and use an interface for logging.
This allows alternative implementations to use whatever logging package
they want.
Currently the interface just mimicks what logrus already implements,
with minor modifications to not rely on logrus itself. I think the
interface is pretty solid in terms of logging implementations being able
to do what they need to.
* Make tracing interface to coalesce logging/tracing
Allows us to share data between the tracer and the logger so we can
simplify log/trace handling wher we generally want data to go both
places.
