Monitor Scope is used to define if an Hosting Subscription and/or Computer is monitored or not.

  The API that notify availability and building from Computer Partition is unecessary and it's
  implementation overuse resources and cause flaky effect on the state of the Computer Partition.

  At the Software Release, the states can be available/building/error, and this state tens to be
  immutable once the software release is finished (it will be available, where building and error are
  transitory states).

  At Computer Partition, we intent to have started/stopped/destroyed instances, where available and
  building were transitory, but they have no practical function as a second report would come quickly
  after. So we may consider that started is actually same as available, in this case, it is a duplicated
  meaning, as you cannot be available w/o been started/stopped.

  computer_partition.building were never used, as the master knew that a partition is been processed,
  so this API were never used.

  Report transitory states are prevent us to determinate the actuall state, considering that the latest
  actuall state is more relevant (started/stopped/destroyed).

This allow the person responsable on for support, load all monitoring URLs from all instances to that may contain a failure.

Stop or Destroyed instances don't required checks.

This cause a lot of headeache during the tests.

If a promise anomaly timeout or return no message, we return error if
the problem is happening for a second time after a second run or if there was already an error.
This will reduce temporary failure.
