Moves the suspend/resume server functionality out of admin_actions into
its own extension. This part of the blueprint v3-admin-actions-split
allows more selective enablement of features contained in the admin
actions extension.
Note that XML api samples are no longer generated because
bp remove-v3-xml-api has been approved.
Partially implements bp v3-admin-actions-split
DocImpact: Adds os-suspend-server extension and moves suspend/resume
functionality out of os-admin-actions into this new extension
