Improve HAFS scripts to use cpreq and cpfs production utilities

Description

Provide a clear and concise description of the requested feature/capability.
From NCO SPA: Improve the HAFS scripts to use cpreq and cpfs production utilities at the next upgrade.

Most of the HAFS v1.0 scripts are using $NCP defined in the ush/hafs_runcmd.sh.inc to copy the data files. Suggest to define the define of NCP as the following that allows $NCP to be redefined and used in different scripts -
NCP=${NCP:-"/bin/cp -p "}

For example, allow jobs to use "cpreq" utility to copy needed input data or use "cpfs" to copy output data files to $COMOU. For example, define NCP="cpfs" in jhafs_gempak.ecf file.

Please refer to WCOSS implementaion doc, page 8 for usage of cpreq and cpfs -

• cpreq is used to copy files that are essential to an application.
• cpfs is used to copy files while ensuring that the whole file has been copied before it becomes accessible so that downstream applications will not attempt to copy or read a partial file.

Based on the NCO SPA's suggestion, the NCP and FCP variables are defined in ush/hafs_runcmd.sh.inc. Under NCO environment, NCP is set as cpreq, FCP is set as cpfs. If desired, they can be easily override at ecf or jjob levels. Meanwhile, the jobs/scripts/ush scripts were improved to use the NCP and FCP commands properly. Please see commit: e4cf12a.
