Rerunning NorESM inside a single submit

[gold2718]

Similar to the CMIP6 production runs, we may sometimes wish to run and restart NorESM3 within a single submission to Betzy or Olivia.
I suggest we use the mechanism built into CIME originally designed for data assimilation.

./xmlchange DATA_ASSIMILATION_SCRIPT=$(./xmlquery --value SRCROOT)/tools/rerun_noresm.py
./xmlchange DATA_ASSIMILATION_CYCLES=3

This script will be available starting in NorESM3 beta02a
