Steps to reproduce:

1. Have a cluster with multiple namespaces.
2. Have pods in them with same names as in other namespaces

Result:

In reality, only one of the namespaces pods container had restarted. Other pods in question have "Restart Count:  0". This can be verified with kubectl in CLI.

There is another example, where we have 1 restart in one namespace and 1 restart in another one. Zabbix reports 2 restart count for all of those pods.
Expected:
To see the correct restart count in Zabbix. Each item should report only that specific namespaces restart count and not combine them.
