            Log:
            add a new basic test which covers the qat service

Recently filed bug reports revealed that SELinux prevents the qat_init.sh
process from the following actions:
 * accessing (syscall = newfstatat) the /dev/hugepages directory
 * creating (syscall = mkdir) the /dev/hugepages/qat directory
 * setting permissions/ownership (syscall = fchownat)

The TC reproduces the situation.

In order to support the qat service functionality, I believe that
SELinux policy should allow these actions. The TC looks for appropriate
policy rules and file context patterns.

The TC covers RHEL-211077 and RHEL-211089.
