Migrate tripleo-packages service to ansible package module
Migrate tripleo-packages service to ansible package module

It is not necessary to exclude specific Ceph packages when running
yum update in Rocky so this change removes the --exclude argument.

Note that it also removes update_cache which is not supported by
the 'package' module.
