82c2368795 Metric format fixes on host/uptime and disk/* 
1. host/uptime, disk/io_time and disk/weighted_io should be
counter/cumulative metrics. SO we have to use the Sum aggregation method
rather than LastValue aggregation method (which will declare the metric
as gauge metric).

2. Renamed label "device" for disk/* metrics to "device_name".
This is to clarify that it is device_name (sda1) rather than device_path
(/dev/sda1)

f9b5e60a43 Add e2e test for NPD 
The first test is a very simple test. It installs NPD on a VM, and then
verifies that NPD reports metric host_uptime in Prometheus format.

63f0e35e56 Implement dynamic problemdaemon registration and initialization. 
Added package problemdaemon. All future problem daemons should be
registered by calling problemdaemon.register().

CLI interfaces will be automatically generated for all registered
problem daemons in the form of "--config.DAEMON_NAME"

5814195ad5 Move apiserver-reporting logic into k8s_exporter. 
Added CLI option "enable-k8s-exporter" (default to true). Users can use
this option to enable/disable exporting to Kubernetes control plane.

This commit also removes all the apiserver-specific logic from package
problemdetector.

Future exporters (e.g. to local journald, Prometheus, other control
planes) should implement types.Exporter interface.

c6c4e80c9d Remove TestGoroutineLeak unit tests. 
We are seeing some flakes on these tests because some goroutine
fluctuation:
https://github.com/kubernetes/node-problem-detector/pull/275#issuecomment-499306727

Removing the tests, as it's robust to test leakage in a soak/stress
test, rather than unit test.
