check_consistency misreads backslash in Cisco IOS config

[travisn08]

Cisco IOS config ends its certificate dump with "\quit". This is always identified as a false diff (reads extra backslash from Golden for some reason).

Hrm, I'll see if I can find an IOS box to repro this on. In the meantime, the action already has a built-in list of strings to ignore (comments and timestamps also generated a lot of pointless diffs), so maybe a good short-term solution is to expose that via params and/or in the config.

When I have some cycles I'll see about doing the latter and get you a workaround (of course if you beat me to it, you're welcome to do so 😄 )
