(Updated July 17, 2024, 7:06 p.m.) Review request for mesos and Benjamin Mahler. Changes ------- Removed DeviceManagerProcess from device_manager.hpp per convention Repository: mesos Description ------- This change introduces the DeviceManagerProcess to help facilitate device access management in cgroups2 via ebpf program file changes. The manager keeps a global state that is checkpointed on change. Device requests can be made to the manager by calling incremental_configure or setup_configure. Note that setup_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, setup_configure cannot be used to add deny 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
