(Updated July 19, 2024, 10:23 p.m.) Review request for mesos and Benjamin Mahler. Changes ------- Pulled out changes related to deconfiguring cgroups device accesses and state recovery. renamed get_diff_state to apply_diff and made it a static function inside DeviceManager only Repository: mesos Description (updated) ------- This change introduces the DeviceManagerProcess to help facilitate device access management in cgroups2 via ebpf program file changes. Device requests can be made to the manager by calling `configure` or `reconfigure`. Note that `configure` should only be used when setting up a cgroup's device access, i.e. it has not requested any device to be allowed/denied before. In addition, `reconfigure` cannot be used to add deny entries containing wildcards. This manager will be made available to all controllers under the cgroups2 isolator, and the GPU isolator.

All unit tests pass Thanks, Jason Zhou
