control: Add a parameter store to Manager

Add a map of names to PropertyVariantValues to the Manager class that
actions can set and read.  This allows one action to use a value from
this parameter map that another action has previously set.

A future use of this is to store a throttle temperature that has to be
calculated, which net_target_increase can then use to make decisions on.
