Hostname digit converted to hostid

[linceaerian]

Hello Maintainers :)

The idea behind

Is not really good: It works in "standard" case but... our hostname are digit... and we use visible name for the name... which lead
to be unable to use this lib as it is ^.^

I would recommend add additional arguments or filter to support hostid or hostname or custom filter, else it can lead to some... inconvenience, ex:

./zabbix-cli -C "remove_host 44432" => I was trying the remove the host with this hostname => changed to hostid, I was lucky the ID did not exist in the Zabbix.

Have a good weekend
