Verify Networks doesn't wait long enough for dhcp response

[Brad Durrow]

We have a dhcp server on our "Public" network segment. Sometimes when we click the "Verify Networks" button we get Green "Verification succeeded. Your network is configured correctly." other times we get Red With messages about DHCP server found.

I refactored dhcp checker to allow it longer timeout.
So to close this bug we need to merge:

    Improve timeout for dhcp response waiter

    Dhcp checker tool is not always receives info
    on dhcp servers in network
    To make checking on network with 400 vlans it takes
    7 min to perform
    Also get_probing_info takes same time for this number of vlans

    Refactor dhcp checker to use pcap

    Scapy packet filtering is slow and blocking.
    Pcap filtering can be used in same thread,
    this allows us to use higher timeout for dhcp offer waiting

    Setup proper logger for dhcp_checker app.
    ERROR level logs will be redirected to stderr
    DEBUG level to /var/log/dhcp_checker.log
