Dougal Matthews c0c4f8a495 Run introspection 20 nodes at a time

Some larger deployments can run into issues when introspecting a large
number of nodes. This patch updates the introspect workflow to run
introspection up to 20 nodes at one time.

The choice of 20 nodes per-batch is based on this comment:

This patch moves introspection into a workflow that starts and waits for
it to finish. This means we can then simply run this workflow with
"with-items" and use Mistrals native support for concurrency limiting.

This tripleoclient patch allows users to change the number of nodes that
are introspected in parallel. https://review.openstack.org/#/c/451228/

     The introspection workflow now accepts an additional parameter
     ``concurrency`` which defines how many nodes should be introspected in
     parallel. The default is 20, but can be changed to any positive integer.
