[rancid] Update configs by an external means

I had the same problem with rancid v1.x using a custom script (written by my predecessor for NX-OS). It cleared up when we migrated to v3.4.1, which had native NX-OS so it’s not clear to me if dumping the custom config fixed the issue or if it were a rancid version issue.
Are you using a current version?

I have started a snwlrancid based on the Mikrotik config fetcher. I
guess I should just throw it up somewhere for others to have a look at.
One thing I've noticed is that the obscured encryption keys in VPN
tunnels change *every time* the config is polled:
So long as it works when it's pasted back in to the firewall then great,
but obviously this is going to be absurdly noisy unless it's replaced
with a placeholder with some post-processing. If it's replaced with a
placeholder then the resulting config cannot be put back in to the
firewall without some tweaking. Personally, working in a team of people
who manage Sonicwalls, partial-RANCID is better than no RANCID at all.
The main roadblock I hit was that the word "exit" just seems to move
around at random, and it's not the same "exit" that does this, there are
loads of exits in the config and any one of them can apparently do it:

I don't have time to work on this at the moment but I will try and make
some time to put what I've done so far on Github or similar.
