lnms config:set breaks regexp by escaping \ to \\

[manonfgoo]

The problem

If I enter a regexp with \ it is saved as \\

expected:

user@host$ lnms config:set   bad_if_regexp.+ "/vlan\s\d+/"
user@host$  lnms config:get   bad_if_regexp
 [
    "/^ng[0-9]+$/",
    "/^sl[0-9]/",
    "/vlan\s\d+/"
]

Observed:

user@host$ lnms config:set   bad_if_regexp.+ "/vlan\s\d+/"
user@host$  lnms config:get   bad_if_regexp
 [
    "/^ng[0-9]+$/",
    "/^sl[0-9]/",
    "/vlan\\s\\d+/"
]

This is actually on the display side, it is stored in the database correctly.

Try lnms config:get bad_if_regexp.2

Hmm, I don't think we want to change that. If we stripslashes() on the json output, it won't be valid json to edit and set back in the database.

It might make sense to have a non-json display.
