Disable zabbix-agent per default

[DennisGaida]

Description of the feature
The Zabbix-Agent comes with this container as your base image (https://github.com/tiredofit/docker-alpine) configures this.

The problem with this base-implementation is that this container makes DNS requests for zabbix-agent every minute. This is spamming the DNS server and actually unnecessary in an environment without Zabbix.

I was able to disable zabbix via CONTAINER_ENABLE_MONITORING: "FALSE" environment variable and believe this should be the default or better documented in this container (since I had to dig out the base image to find this variable). Or: The default zabbix config could be to not do a DNS request for zabbix-agent every minute?

Benftits of feature
No more zabbix-agent DNS spam

Thanks, Since my clients and I are the primary user of these images I leave Zabbix Agent by default on. I feel my README is descriptive enough that there are other options that may or may not need to be configured.

I unfortunately don't know much about changing the interval that the DNS request is being made for, but it sounds like you have resolved with the environment variable to disable entirely, which I feel is a better approach to save on resources. Going to close this on that basis.
