Dag Wieers 03af450bdc Module to assist users in understanding Ansible
After helping someone on IRC he was interested to have this debug module in upstream. This module simply 'prints' a message, and can be ordered to fail if needed. It helps to troubleshoot or understand inventory/facts issues and/or experiment with statements and conditions using only_if.

Here is a small example playbook:

```yaml
- hosts: all
  tasks:
  - local_action: debug msg="System $inventory_hostname has uuid ${ansible_product_uuid}"
  - local_action: debug msg="System $inventory_hostname lacks a gateway" fail=yes
    only_if: "is_unset('$ansible_default_ipv4.gateway')"
  - local_action: debug msg="System $inventory_hostname has gateway ${ansible_default_ipv4.gateway}"
    only_if: "is_set('$ansible_default_ipv4.gateway')"
```

outputting:
```
[root@moria ansible]# ansible-playbook -v -l localhost:x220 test6.yml

PLAY [all] *********************

GATHERING FACTS *********************
ok: [localhost]
ok: [x220]

TASK: [debug msg="System $inventory_hostname has uuid $ansible_product_uuid"] *********************
ok: [localhost] => {"msg": "System localhost has uuid d125a48c-364f-4e65-b225-fed42ed61fac"}
ok: [x220] => {"msg": "System x220 has uuid d125a48c-364f-4e65-b225-fed42ed61fac"}

TASK: [debug msg="System $inventory_hostname lacks a gateway" fail=yes] *********************
failed: [localhost] => {"failed": true, "msg": "System localhost lacks a gateway", "rc": 1}
ok: [x220] => {"msg": "System x220 has gateway 192.168.1.1"}

PLAY RECAP *********************
localhost                      : ok=2    changed=0    unreachable=0    failed=1
x220                           : ok=3    changed=0    unreachable=0    failed=0

```

I had some other plans for the module, like displaying host inventory and complete inventory to help understand inventory and facts modules, but that would require an action-plugin for transfering inventory information etc... And I am not sure this is wanted/best done in a module.

Dag Wieers fedfd18774 Fix gather_facts assumption that SETUP_CACHE for a host is empty
We now check explicitely for 'module_setup' in the SETUP_CACHE in order to avoid skipping setup because SETUP_CACHE was populated some other way. Other modules can implement the same mechanism to test if they've already run.

This closes #1206.

Dag Wieers f11ab4383a Make ignored/skipped different from changed
Since a skipped/ignored action is _very_ different from actual changes to a system, it always bothered me that  it was not easily distinguishable when skimming the output. This change makes ignore/skip a different color, and I chose cyan. Contemplated using dark-gray/blue, but prefered something that is readable with most terminal colors.

Dag Wieers 1d27909ec0 Added a fail module in order to fail execution on certain conditions
In some cases you may want to deliberately fail the execution of a playbook. In our provisioning workflow we want to have safeguards in place to avoid provisioning systems that are already in production. Since we reboot physical and virtual systems, it is mandatory we take all the precautions to prevent accidental provisioning.

So in our use-case we have the following at the very start of the provisioning playbook:

    ### Safeguard to protect production systems
    - local_action: fail msg="System is not ready to be staged according to CMDB"
      only_if: "'$cmdb_status' != 'to-be-staged'"

and we repeat the same task in the (separate included) play that takes care of (re)booting the system using our own boot-media, so that it cannot be accidentally separately run by someone.

Dag Wieers 20c1a67711 Abort a play at the start when no hosts matches, or no hosts are remaining
This change makes a distinction between no_hosts_matched and no_hosts_remaining.

In both cases we do not start facts-gathering, or run any tasks.

In the case that there are no more hosts remaining, we abort running tasks and abort the playbook.

I also cleaned up the leftovers from the previous patchsets, as these are no longer required.

This closes #1187.

Example playbook:

```yaml
---
- hosts: emptygroup
  tasks:
  - action: command date
  - action: command false

- hosts: all
  gather_facts: False
  tasks:
  - action: command ls
  - action: command false
  - action: command true

- hosts: all
  tasks:
  - action: command true
  - action: command false

- hosts: all
  tasks:
  - action: command pwd
```
