standardize container health checks into scripts for all docker containers

[mmguero]

The docker-compose.yml and Kubernetes health checks do various things to gauge container health, but I would like to standardize how this is done.

I'd like every container to have a container_health.sh script installed to /usr/local/bin. This script should exit with an exit code of 0 if things are healthy/up/ready and non-zero if they are not.

In addition to creating the scripts, replacing the health checks in the compose file and Kubernetes manifests to call the scripts should be done.

The zeek container already has one of these you could use as reference. Also, the ready function in the API would be a good example of things to check.

To clarify, this is already done for the logstash and zeek/zeek-live containers.
