lib: add 'no ... remark LINE' commands

Implement the commands `no ... remark LINE` for cisco and zebra style
access lists to match `ipX prefix-list description LINE` command set.

It useful when you just want to go through the command history and
prepend a `no` to a `remark` or `description` command. Example:

```
access-list foo remark just another acl
!
! ...
!
! Suddenly we decide we no longer think that remark is useful,
! lets press up key to find that line in history and append `no`:
no access-list foo remark just another acl
```
