Few minor editorial updates to OTN Topology YANG model

[italobusi]

1. the client-svc presence container should be outside the te presence container according to https://github.com/ietf-ccamp-wg/draft-ietf-ccamp-flexigrid-yang/files/10510430/new-ml-topology-models-00.txt

   OLD

   +--rw nt:link* [link-id]
      +--rw tet:te!
         +--rw te-link-attributes
            +--rw otnt:client-svc!
            +--rw interface-switching-capability*

   NEW

   +--rw nt:link* [link-id]
      +--rw otnt:client-svc!
      +--rw tet:te!
         +--rw te-link-attributes
            +--rw interface-switching-capability*
                   [switching-capability encoding]
   
   +--rw nt:termination-point* [tp-id]
      +--rw otnt:client-svc!
      +--rw tet:te!
         +--rw interface-switching-capability*
                 [switching-capability encoding]

2. c/otn-ltp/otn-link-tp/ since the acronym ltp is not used in RFC8795 for YANG attribute names

3. c/otn/otn-bandwidth/ for bandwidth augmentations for alignment with MW topology and other cases (otn-node, otn-link, otn-link-tp, otn-label-range)
