SRIOV: ESwitchManager should handle multiple NICs per physical net

[Oleg Bondarev]

Commit 46ddaf4288a1cac44d8afc0525b4ecb3ae2186a3 made it possible to specify multiple NICs per network.
However ESwitchManager now stores only one EmbSwitch per physical net (the last one).

    Fix SR-IOV binding when two NICs mapped to one physnet

    Because ESwitchManager._create_emb_switch stores one EmbSwitch per
    physnet, there is only last EmbSwitch works if two NICs was configured
    for one physnet:
    physical_device_mappings=physnet2:ens3f0,physnet2:ens3f1

    This patch makes ESwitchManager.emb_switches_map store a list of
    EmbSwitch for physnet.

    Also fixed usage of singleton ESwitchManager class in tests by
    adding cleanup.
