Add sudo argument to Cell.all

[yohanboniface]

A user must have root access to list interfaces, but we don't
want to run python as root, which would be a big security issue.
So this PR allows to only give sudo access to iwlist to the user
running python.

I haven't see any unittests on Cell.all so I haven't added any. If I missed
something, please point me to it :)

Hi @yohanboniface,

I think this is good.

Don't you need the sudo arg on other calls?

Good question? :)

Answer is not yet, but certainly in the near future ;)

@splite07, I guess we'll also need sudo to activate a given cell?

[fheslouin]

Yes you are right!
We will need to have sudo args on save() call, activate() call and probably delete() call

[yohanboniface]

OK, I'll update my PR this way. :)
@rockymeza adding sudo kwarg to all those method sounds ok for you?

[rockymeza]

@yohanboniface, I think it's ok. I don't know what else we would do. I would love to have some unit tests that mock subprocess just to make sure that this is working. (I know it didn't have any before, sorry!)
