Clean zabbix.list file before switching to another version

[hatifnatt]

If file will not be cleaned you'll end up with something like this:

deb http://repo.zabbix.com/zabbix/3.0/debian stretch main
deb-src http://repo.zabbix.com/zabbix/3.0/debian stretch main
deb http://repo.zabbix.com/zabbix/3.4/debian stretch main
deb-src http://repo.zabbix.com/zabbix/3.4/debian stretch main

• In case of upgrade there is no reason to preserve repo for old version.
• In case of downgrade you will be forced to specify version for every installed zabbix package like that:

  zabbix:
  lookup:
  version_repo: '2.4'
  server:
    version: '2.4.*'
  agent:
    version: '2.4.*'

  but usually you just need to install latest available version.

• I think preserving old repo lines is not what you expect when you change repo version in formula.
