Fix missing msg argument

ansible_ec2_instance-id key incorrect

Fix for #7368 breaks peering connections. Unreak them.

removed port from domain name qualification, fixes #7941

Fixes #7843

The following patch adds a missing 'msg=' syntax. An exception is raised
in ansible if this block is reached during the execution of the module

    TypeError: fail_json() takes exactly 1 argument (2 given)

With the 'msg=' added, you get a more informative error. For example

    msg: No settings provided to update_domain().

Callback plugin cleanup

win_service module updates and tests

Support a whitelisted subset of jinja2 template options

ansible_ec2_instance-id should be ansible_ec2_instance_id

fatal: [*IP*] => One or more undefined variables: 'dict object' has no attribute 'ansible_ec2_instance-id'

Adds support for Cloudwatch detailled monitoring in ec2_lc module.

This reverts commit 2493020d.

Fixes #7712

nova.py: indented and sorted JSON output

Correct typo: 'receords' -> 'records'

Correct typo: 'additioanl' -> 'additional'

nova.py: Remove DOCUMENTATION block

- auth_system
- region_name

These are config settings that could be left out in many scenarios, but
the current code is requiring them. With this in place, I can get by
with this minimal .ini file:

```ini
[openstack]
version=1.1
auth_url=http://{keystone_host}:5000/v2.0
project_id=web
username={username}
api_key={password}
```

I should read more than a sentence at a time when I'm correcting typos—sorry for the typo correction spam ;)
