QID 750699: SUSE Enterprise Linux Security Update for cryptctl (SUSE-SU-2021:2136-1)

This update for cryptctl fixes the following issues: update to version 2.4: - cve-2019-18906: client side password hashing was equivalent to clear text password storage (bsc#1186226) - first step to use plain text password instead of hashed password.
- move repository into the suse github organization - in rpc server, if client comes from localhost, remember its ipv4 localhost address instead of ipv6 address - tell a record to clear expired pending commands upon saving a command result; introduce pending commands rpc test case - avoid hard coding 127.0.0.1 in host id of alive message test; let system administrator mount and unmount disks by issuing these two commands on key server.
