Cause: cluster-baremetal-operator uses the incorrect logging library Consequence: the command line arguments are not consistent with other Operators and not all kubernetes library logs will get out. Fix: switch the logging library. Result: consistent command line arguments and better diagnostic logging.

Description sdasu 2020-12-09 18:15:19 UTC 
Description of problem:
We are using the zap logging library, and passing a logger to the controller-runtime. Then we use calls like `r.Log.V(1).Info(...)` to emit messages. There is some question about whether those messages are going to make it to normal log output, since the default verbosity is `0`.

We also don't provide a command line option to control the log level. We should be able to have a default of 1 and provide other levels using, for example `-v=4`.

Other kubernetes libraries use k8s.io/klog/v2 and may be using logging calls that don't comply with how we configure logging. We may therefore be losing information when those log messages are not printed. We should replace zap with klog.
