Added test cases

concurrently; they block by queueing up at the DB-writer, which is a ZMQ
proxy to the Sqlite database

* dag.spawn_child now clones jobs in a more sane way; fixed bug related
to job_id being sent over the wire as None

* improved logging

* Fixed deserialize bug when job_id is None (for new jobs)

* added test case for concurrent BalsamJob insertions to database from a
single mpi4py applicaiton, where all ranks are concurrently calling
save() with new jobs

cli_commands: fixed small user error message bug
model saving: more robust retry: wait and check if save succeeded in
spite of the exception

DAG functional tests; bugfixes in launcher and runners. mpi_ensemble reads envs directly from database
