59cfa127e2 snapshotctl: allow to write stats
To send statistics about snapshot merge times, snapshotctl will take
care of packing and sending all the information.
Allow snapshotctl to do so by creating an sepolicy exception.

Test: statsd_testdrive

667b71010a snapshotctl: talk to bootcontrol HAL

070d35916f Allow snapshotctl to create ota_metadata_file.
When snapshotctl merge is called on sys.boot_completed
and /metadata/ota/state does not exist, it now tries
to initialize it by creating one.

Test: no selinux denials on boot

f375337cc8 Add rules for snapshotctl
snapshotctl is a shell interface for libsnapshot. After rebooting
into an updated build, on sys.boot_completed, init calls
snapshotctl to merge snapshots. In order to do that, it needs to:
  - Talk to gsid to mount and unmount COW images
  - read the current slot suffix to do checks (and avoid merging
    snapshots when it shouldn't).
  - read / write OTA metadata files to understand states of
    the snapshot
  - delete OTA metadata files once a snapshot is merged
  - collapse the snapshot device-mapper targets into a plain
    dm-linear target by re-mapping devices on device-mapper

Test: reboot after OTA, see merge completed without denials
