[develop] Ensure arbitrary restart_interval numbers in model_configure

[chan-hoo]

DESCRIPTION OF CHANGES:

• To ensure arbitrary numbers for restart_interval, the unnecessary parameter value -1 is removed from the template parm/model_configure.
• The WE2E test is updated with restart_interval: 1 2 5, which creates the restart files at fhr=1, 2, and 5.

@MichaelLueken, Thank you! I forgot to add [develop] to the title.

@chan-hoo These changes look good to me. However, the specify_RESTART_INTERVAL WE2E test was ran on Cheyenne. This test failed due to running over the walltime limit. Please increase WTIME_RUN_FCST: to allow the test to run on this machine (01:30:00 or 02:00:00 should allow this test to run to completion).

[MichaelLueken]

Thank you very much, @chan-hoo, for addressing my concern! A rerun of the specify_RESTART_INTERVAL test on Cheyenne is now successfully passing. Approving this work and launching the Jenkins tests.

I have run the test case modified in this PR on Hera, and it does produce restart files for forecast hours 1, 2 and 5 so approving.

[MichaelLueken]

The Jenkins tests have passed, two approvals have been given, and there are no outstanding comments, so I will now move forward with merging this work.
