    Caches switch port, VLAN, VSID setting data WMI objects

    The Hyper-V Neutron Agent, during its first loop, will iterate
    over all the switch ports, checking their proper setup. In order
    to avoid wasting time querying the necessary WMI objects for each
    port, they are cached first.

    Initialises the cache for the mentioned objects. Thus, they will be
    retrieved from the cache while processing 'foo' port.

    This will also improve the general performance of the agent.

    (cherry picked from commit 2abeee743ca02b1263bf7fdea36509bab52b23d8)
