    Adds Hyper-V dynamic memory support

    Blueprint: hyper-v-dynamic-memory

    Memory overcommit in Hyper-V is handled with a feature called dynamic
    memory (memory ballooning). This change adds a configuration option to
    enable it.

    The value of dynamic_memory_ratio expresses the ratio between the total
    RAM assigned to an instance and its startup RAM amount. For example a
    ratio of 2.0 for an instance with 1024MB of RAM implies 512MB of RAM
    allocated at startup.

    Unit tests have been added for this feature as well.
