stats: fix prometheus exporter crash on large number of FIB entries

Type: fix

Currently, prometheus exporter may crash because of memory exhaustion
when dumps metrics if the FIB contains large number of routes.

With this fix, increase memory size for prometheus exporter to be able
to handle large number of FIB entries.
