"""Power parameters. Each possible value of a Node's power_type field can
be associated with specific 'power parameters' wich will be used when
powering up or down the node in question. These 'power parameters' will be
stored as a JSON object in the Node's power parameter field. Even if we want
to allow arbitrary power parameters to be set using the API for maximum
flexibility, each value of power type is associated with a set of 'sensible'
power parameters. That is used to validate data (but again, it is possible
to bypass that validation step and store arbitrary power parameters) and by
the UI to display the right power parameter fields that correspond to the
selected power_type. The classes in this module are used to associate each
power type with a set of power parameters.
To define a new set of power parameters for a new power_type: create a new
mapping between the new power type and a DictCharField instance in
`POWER_TYPE_PARAMETERS`.
