Spurious failed routing engine from some JunOS devices

This commit:


Has caused a large number of my juniper devices (~25) to start spuriously reporting a failed routing engine.

It looks like in the code that was removed there was a filter that prevented some objects in the fru mib from being polled:

preg_match('/Routing Engine [0|1]/' 

That has not been preserved in the YAML version.

I think the “right” way to implement the filter is to look at jnxFruSlot - it seems to be set to a negative number for the non-existent routing engines.
