L3 conntrack helper: Use singular name consistently

We use singular form for delete command argument in all places.
This commit replaces conntrack-helper-ids with a singular form.
The only visible change is a fix for the help message below.

  openstack network l3 conntrack helper delete
      <router>
      <conntrack-helper-ids>
      [<conntrack-helper-ids> ...]
