Implement AutoScaling UpdatePolicy

Registered by Steven Hardy

AWS provide an UpdatePolicy attribute which can be used with AutoScaling groups to specify how changes to the launch configuration or subnet are rolled out. Seems like a useful thing to add, somewhat related to the rolling-updates work but not specific to metadata.

Whiteboard

(shardy) based on the number of review comments requiring rework on https://review.openstack.org/#/c/43571/, and the lack of communication indicating a revised patch is imminent, this looks like it will miss feature freeze, so deferring to Icehouse.
