@brief Implement the session create method
@param ctx The method context.
@return -1 upon error; zero if successful, and if a STATUS message has
been sent to the client to indicate completion; a positive integer if
successful but no such STATUS message has been sent.
Method parameters:
- a hash with some combination of the following elements:
- "user_id" -- actor.usr (au) ID for the user to cache.
- "org_unit" -- actor.org_unit (aou) ID representing the physical
location / context used for timeout, etc. settings.
- "login_type" -- login type (opac, staff, temp, persist)
- "workstation" -- workstation name
