Excessive/erronous host group creation

[paalbra]

If multiple hosts are missing a host group and this host group is missing from Zabbix only the first creation of the host group will be successful. The others might lead to loads of error messages.

Maybe updating zabbix_hostgroups somewhere here does the trick:

zabbix-auto-config/zabbix_auto_config/processing.py

Lines 698 to 701 in 9ff0b81

	zabbix_hostgroup_id = zabbix_hostgroups.get(hostgroup_name, None)
	if not zabbix_hostgroup_id:
	# The hostgroup doesn't exist. We need to create it.
	zabbix_hostgroup_id = self.create_hostgroup(hostgroup_name)
