[VAPI-4801] Fix deprecation links in the api-explorer

This change fixes the following three issues:
1. /api/session is not linked to /rest/com/vmware/cis/session (due to the lack
   of /cis in the new representation)
2. vmw-task=true (i.e. @TaskOnly) operations are not linked properly
3. the new token-exchange is not linked to the old one (there is no metadata
   for that link)

It also fixes the filename used in the deprecation path by removing the
'api_' prefix. This doesn't affect the api-explorer in any way.

Testing done: switched the 3 affected files on a deployment and verified
that operations are now properly linked.
