common: fix installation condition

common: fix installation condition

Problem: we could end up in situation where we would install a package
on a machine that does not have the right repo enabled. Because the
condition was set to OR we weren't pinning a particular host but just a
condition. Let's say someone sets 'ceph_origin == "distro"', this would
try to install OSD packages on Monitors.

Solution: use a AND condition to first pin to the group_name (which
identifies a set of hosts) AND then after this one of the installation
condition.
