Required for all PRs:

resolves #9983

This PR aims to fix thread-safety for the ifname plugin. Before it used only one instance of gosnmp for all agents, but that doesn't work out if multiple agents need to be processed at the same time. My addition creates a gosnmp instance for each agent, so no threading problems occur.
