Moshe Levi ce102be8fc Enhance PCI passthrough whitelist to support regex ...

This patch introduces a new syntax for the address key:
    "address":{ "domain": <regex_domain>, "bus": <regex_bus>,
                "slot": <regex_slot>, "function": <regex_function> }

Example for the regular expression syntax:

    This allows allocation of VFs whose functions are from 2 upwards:
    pci_passthrough_whitelist= {"address":{"domain": ".*",
                                           "bus": "02", "slot": "01",
                                           "function": "[2-7]"},
                                "physical_network":"net1"}

    This allows allocation of VFs whose slots are between 1 and 2:
    pci_passthrough_whitelist= {"address":{"domain": ".*",
                                           "bus": "02", "slot": "0[1-2]",
                                           "function": ".*"},
                                "physical_network":"net1"}
