Moves create_backup functionality out of admin_actions
into its own extension. This is part of blueprint v3-admin-actions-split
which 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-api-admin-actions-split
