openSUSE Leap 15.3 Important: Cryptctl Password Client Issue

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.
