Update utest and ci (#603)

* Update utest script: Handle global, regional, and coupled tests
* Update CI workflow: Instead of saving the docker image (~730 MB) as an artifact, only save the executable (~77 MB)
* Add regional thread and decomposition tests to CI
* Add coupled restart test to CI
* Fix to run threads on its own core in ec2 for thread tests
* Use a slightly different ubuntu-hpc image to match the uid and gid within ec2 instances
* Exclude L127 control test temporarily
