Problem description: According to the log files (debug level =4), for agent2 the HostInterfaceItem remote command is executed only on startup, but for the standard zabbix-agent this remote command is executed each RefreshActiveChecks period.

According to specification of ZBXNEXT-1740 the HostInterfaceItem remote command should be considered as an active check, so it should be checked once per RefreshActiveChecks interval, as it is currently done for the standard zabbix-agent.

Steps to reproduce:

1. Have a Zabbix instance with agent2 configured. Agent2 is not running
2. Edit agent2 config - spefify the following parameters:
        DebugLevel=4
        Comment parameter "Hostname"
        HostnameItem=system.run[echo New_Host_Name] 
        HostMetadataItem=system.run[echo Host_Meta_Data]
        HostInterfaceItem=system.run[echo Zabbix]
        RefreshActiveChecks=60
        Plugins.SystemRun.LogRemoteCommands=1
3. Start agent2 and wait for a couple of minutes
4. Open agent2 log file

Result: According to the agent2 log file agent2 launches HostInterfaceItem remote command only on startup, but HostMetadataItem - each 60 seconds.
Expected: Same as in case of standard zabbix-agent, agent2 should execute both HostInterfaceItem and HostMetadataItem once per RefreshActiveChecks interval.
