Support setting pacemaker resource defaults

[jistr]

This patch adds initial support for pacemaker resource defaults. Similarly as other pacemaker resource types in this module, it doesn't yet prefetch already created resources.

The resource default can either be created directly via pcmk_resource_default type, or in bulk via pacemaker::resource_defaults class.

Tested together with https://review.openstack.org/218931.

For sanity, tested:

pcmk_resource_default {"resource-stickiness":
  value => '200',
  ensure => present,
}

and works as expected. +1 to merge.

Thanks Crag :) I added the debug statement and tested in a similar way, here's the output:

Info: Applying configuration version '1441100685'
Debug: Running pcs resource defaults | grep '^mydefault: myvalue$'
Debug: Running pcs resource defaults mydefault='myvalue'
Notice: /Stage[main]/Main/Pcmk_resource_default[mydefault]/ensure: created
