JSA::Submission: correct spelling of chunking
jsahpxobs: submit to CADC only non-chunking jobs

Jobs expected to chunk are placed into a separate hash and not
passed to the submit_jobs subroutine.
Add interface module for local jsa_proc system

The new module JSA::Proc will contain routines for interacting
with the new JSA local processing system.  It currently contains
a dummy implementation of a subroutine add_jsa_proc_jobs
for adding jobs to the system.  This is called by jsahpxobs with
the jobs submitted to CADC and those to be run locally.
The CADC recipe instance identifiers are now added to the hash
by the JSA::Submission::submit_jobs subroutine to allow this
information to be added to the local system.

JSA::Proc: implement add_jsa_proc_jobs subroutine
