[c-nsp] parser config cache interface - stable/safe?

Running SRA/SRB/SRD, we have seen a few instances (>5) of the "real" running config being out of sync with the output of show run interface.  Problem was easily cleared by removing/reading the parser cache command.

Have not tested the scp results under those circumstances.

The benefit of the config cache is significant.  Loaded chassis without cache sometimes take maybe 30-60 seconds to begin outputting from a show run.
