create IMS.rc or JMS.rc directly on run_dir

[weiyuan-jiang]

The present PR is a continuation of #733.
It is not safe when multi ldas_setup run at the same time and using the same IMS.rc or JMS.rc. This PR creates the files on the run directory.

@weiyuan-jiang : Can you please clarify if the present PR (#740) is a correction of #733? That is, should #740 be considered a continuation of #733?
Or is #740 something that you just happened to think of and then out of convenience you added the present changes on the branch associated with #733? If so, #740 and #733 aren't really related.
Given the re-use of the branch name from #733, the introductory comment above is a bit unclear

[CORRECTED 22 March 2024: original comment mistakenly referred to #739 instead of #733.]

@gmao-rreichle , #739 and #740 are unrelated. This PR (#740) is continuation of PR #733 that was merged last night. I had some concern to create IMS.rc and JMS.rc on temporary directory. If multi ldas_setup are running, there would be conflict.
