qa: install ceph-osd-classic and ceph-osd-crimson

- qa/packages/packages.yaml: add ceph-osd and ceph-osd-classic to
  packages/packages.yaml, so that the "install" task can install
  ceph-osd-classic by default, this preserves the existing behavior.
- qa/suites/crimson-rados: install ceph-osd-crimson instead of
  ceph-osd-classic. adding them to exclude_packages and extra_packages
  to task.install allows us to customize the packages to be installed
  when performing the "install"
  task.
- qa/suites/crimson-rados-experimental: likewise.
