backup: Add new domain:checkpoint access control

Browse Source 
Creating a checkpoint does not modify guest-visible state,
but does modify host resources.  Rather than reuse existing
domain:write, domain:block_write, or domain:snapshot access
controls, it seems better to introduce a new access control
specific to tasks related to checkpoints and incremental
backups of guest disk state.
