Only list the services supported
Don't put in unncessary required: false
Use better formatting for the example

Even though others are possible, fail early on unsupported ones.
Make more lookup plugins happy with newstyle variables.  Not quite done, but this fixes up with_items/with_nested/file/fileglob.
Make more lookup plugins tolerant of new variable system, with a little better 'do what I mean' logic to resolving
what happens if you get a string back as a template result.
Remove a debug statement.

Ec2 vol improvements
Allow '.yml'/'.yaml' extension on group_vars files.

Look for a file with the base name of the group/host, first without
a file extension, then with a '.yml' extension, and, finally, with
a '.yaml' extension, loading vars from only the first one found.

Merge pull request #2608 from lwade/ec2zone

Add availability zone parameter
copy action plug-in check mode respects force=no

The copy action accepts force=no, which tells it not to replace an
existing file even if it differs from the source.  The copy action
plug-in wasn't respecting this option when operated in check mode, so it
would report that changes are necessary in check mode even though copy
would make no changes when run normally.

Runner._remote_md5 was changed to make the logic for setting rc perhaps
a little more clear, and to make sure that rc=0 when the file does not
exist.
