Description of problem:
  Commit 76ddcbc271[1] breaks conditions in install_on_redhat.yml[2] related to following tasks (and maybe also something else):
    * install distro or red hat storage ceph mon
    * install distro or red hat storage ceph osd
    * install distro or red hat storage ceph mds
    * install distro or red hat storage ceph-fuse
    * install distro or red hat storage ceph base
  
  Now the condition for example for installation of 'ceph-mon' package looks like this:
    when:
    - mon_group_name in group_names
      or ceph_origin == "distro"
      or ceph_custom
  Which means, install ceph-mon package on system which is in mon group *OR* if ceph_origin == "distro".
  There should be logical AND instead of OR.

Version-Release number of selected component (if applicable):
  ceph-ansible-2.2.6-1.el7scon.noarch
  It was broken by commit 76ddcbc271[1].

How reproducible:
  100%

Steps to Reproduce:
1. Try to create Ceph cluster via ceph-ansible (with ceph_origin set to "distro").

Actual results:
The Ceph create cluster task fails on following (and similar) error, when try to install ceph-osd on monitor node:
  fatal: [mon1.example.com]: FAILED! => {
    "changed": false,
    "failed": true,
    "invocation": {
        "module_args": {
            "conf_file": null,
            "disable_gpg_check": false,
            "disablerepo": null,
            "enablerepo": null,
            "exclude": null,
            "install_repoquery": true,
            "list": null,
            "name": [
                "ceph-osd"
            ],
            "state": "present",
            "update_cache": false,
            "validate_certs": true
        }
    },
    "msg": "No package matching 'ceph-osd' found available, installed or updated",
    "rc": 126,
    "results": [
        "No package matching 'ceph-osd' found available, installed or updated"
    ]
  }

Expected results:
  ceph-ansible will install particular ceph packages on particular node accordingly to goroup/role assigned to the node
