[heroes] support for package installation in salt

Hello, I added support for package installation in salt. Right now I added aaa_base-extras in pillar/common.sls that will be installed in all machines. Assuming we have a proper role grain in a machine set up, we can add packages under pillar/role/$role.sls as well to get it installed on a specific role as well. There is support also for installing packages from a specific repository via the fromrepo attribute, eg zypper: packages: nrpe: fromrepo: openSUSE:infrastructure Let me know if you need further info or if you have further ideas -- Theo Chatzimichos System Administrator SUSE Operations and Services Team
