Many filters use data from ``scheduler_hints``, that is defined in the moment of
creation of the new server for the user. The only exception for this rule is
|JsonFilter|, that takes data in some strange difficult to understand way.
|JsonFilter|, that takes data from the schedulers ``HostState`` data structure
directly. Variable naming, such as the ``$free_ram_mb`` example above, should
be based on those attributes.
The |RetryFilter| filters hosts that have already been attempted for scheduling.
It only passes hosts that have not been previously attempted.
