Add generic output related input variables to CM scripts

[arjunsuresh]

I think it'll be good to make the below input_mapping generic to all CM scripts as it can avoid a lot of redundant code in individual CM scripts and also make the variable names consistent.

--outfilepath: CM_TMP_OUTFILE_PATH
--outdirpath: CM_TMP_OUTDIR_PATH (This will be the path to the cache for scripts using cache)
--outfilename: CM_TMP_OUTFILE_NAME
--outdirname: CM_TMP_OUTDIR_NAME
