Changelog:
- Zabbix-3.0 compatible
- Merge changes from the original pyzabbix 0.7.4 into zabbix-cli/pyzabbix
- Upgrade command create_notification_user to accept a 'remark' string.
- Upgrade command create_host to use regular expressions in the [proxy] parameter. This can be used to define the group of proxy servers that will be used to find the zabbix proxy that will monitor the new created host.
- Disable the use of JSON exports until https://support.zabbix.com/browse/ZBX-10607 gets fixed. Only XML exports work now.
