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"
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.
If --system-log-monitors or --custom-plugin-monitors are not
specified, npd gave us unclear message.
This patch adds the validation and clear error message.

1. Why is this change necessary ?
The program avoids changing hostname and the variable name "Options" is changed to
"options". Also, added more comments and formatted. Removed hostname in options since
it will not be changed in tests.
2. How does this change address the issue ?
While the program is being run, the hostname is not changed. And options can't be
accessed outside(not exported).
3. How to verify this change ?
Run, make test
