Is your feature request related to a problem? Please describe.

After we switched to Zowe Launcher as start program of Zowe, we want to automatically configure ARM policy for Zowe.

Describe the solution you'd like

• Define ARM policy to SAMPLIB, creating ARM policy into configuration step.
• Define exits for the Zowe Launcher program (IXCARM Macro), save into loadlib, make it APF enabled and modify PROCLIB to add ARMREG/DEREGISTER step. (needs further verification).
• We may need to modify how to clean up the ARM policy for Ansible automation.
• Prepare documentation to register z/OSMF with ARM, including how to define ARM policy and add ARMREG/DEREGISTER step to z/OSMF procs IZUANG1 and IZUSRV1.
• A properly ARM enabled Zowe job should show ARMELEM in SDSF.ST panel.
