The plugin was not handling 404 Not Found correctly when looking
up pods and namespaces. In this case, we assume the pod/namespace
was deleted, annotate the record with whatever metadata we have,
and cache the fact that the pod/namespace is missing so we don't
attempt to look it up again.
In addition, the plugin was not handling error 429 Busy correctly.
In this case, it should also annotate the record with whatever
metadata it has, and _not_ cache anything. By default the plugin
will retry every 5 seconds to connect to Kubernetes. This
behavior is controlled by the new config param `busyretryinterval`.
This commit also adds impstats counters so that admins can
view the state of the plugin to see if the lookups are working
or are returning errors. The stats are reported per-instance
or per-action to facilitate using multiple different actions
for different Kubernetes servers.
This commit also adds support for client cert auth to
Kubernetes via the two new config params `tls.mycert` and
`tls.myprivkey`.

Was not working on python3 - must use `encode()` to convert the
string to a `bytes` object.
Also run the server with python -u to make sure we get the log
output from the kubernetes test server.
Fix lnrules for CONTAINER_NAME
Add pkg check for lognorm >= 2.0.3 so we can set the macro
to enable ln_loadSamplesFromString
Add some reasonable default values for parameters, such as
kubernetesurl https://kubernetes.default.svc.cluster.local:443
Clean up sample.conf configuration file
Add test for mmkubernetes, including mock kubernetes service
