kubernetes - check out filebeat on network volumes

While I took care of the issues with using inotify, I should look more specifically at filebeat on Malcolm and whether or not it's supporting reading from network drives correctly in the case of something like kubernetes.

See:

• Can’t read log files from network volumes

• Filebeat stops processing log entries after "Read line error: file inactive" elastic/beats#1974

• Filebeat issue with ready logs from NFS elastic/beats#2056

• Add support for network volumes in Filebeat elastic/beats#5876

I don't know it's going to be an issue... but I don't know it's not going to be an issue. Sort of related to idaholab#102, we could replace it with fluent-bit if it works better (if we have a problem).
