Fix "DB version too old (sssd)

When running commands such as usermod a warning message like the following will be shown:

[sss_cache] [sysdb_domain_cache_connect] (0x0010): DB version too old [0.22], expected [0.24] for domain implicit_files!
Higher version of database is expected!
In order to upgrade the database, you must run SSSD.
Removing cache files in /var/lib/sss/db should fix the issue, but note that removing cache files will also remove all of your cached credentials.
Could not open available domains

The suggested fix is to remove cache files in /var/lib/sss/db:

rm -rf /var/lib/sss/db

This requires to restore the db directory and config file:

# create them manually
mkdir /var/lib/sss/db
touch /var/lib/sss/db/config.ldb

# or reinstall sssd-common
dnf reinstall sssd-common
