This is caused by a command in the audit pipeline (for example
ps -ef | grep kube-apiserver) failing. The causes of this failure
in my testing is usually a missing config file.
Extensive refactor and correction in verification code to check for
config files and binaries.
Replace joncalhoun/pipes with implementation using exec.Cmds so errors
are visible and can be handled when audit pipeline commands fail.
Change some audit commands
from: ps -ef | grep <cmd> | grep -v
to: ps -C <something> -o comm,args --no-headers
which is simpler to work with.
