vdsmcli: Add a contrib command line client alternative

This command line client is built by hand for the convenience of
developers and requires the click library:
    pip install click

It easily supports commands and subcommands. For example:

    vdsmcli network

is a command and 'show' and 'add' are its subcommands.

Examples:

    toniel602 ~ # vdsmcli network show -k nics -k networks
    ============================================= Nics
    eth6
    eth5
    eth4
    eth3
    eth2
    eth1

    ============================================= Networks
    foo

or
    toniel602 ~ # vdsmcli --verbode --pprint network show -k networks
    ============================================= Networks
    ===============
    foo
    ===============
    {'addr': '',
     'bootproto4': 'none',
     'bridged': False,
     'gateway': '',
     'iface': 'bond42',
     'interface': 'bond42',
     'ipv6addrs': ['2620:52:0:223c:201:a4ff:feac:8796/64',
                   'fe80::201:a4ff:feac:8796/64'],
     'ipv6gateway': 'fe80:52:0:223c::3fe',
     'mtu': '1500',
     'netmask': ''}

addition
    toniel602 ~ # ./cvdsm.py -v -p network add foo --bridgeless --nic eth4
    --nic eth5 --bond bond42
    Networks: {u'foo': {'bonding': u'bond42', 'bridged':
False}}
    Bonds: {u'bond42': {'nics': (u'eth4', u'eth5')}}
    Succeeded. Done

One could extend it with a vm command so that it was easy to do:

    vdsmcli vm hotplug 34f5f608-91ed-48d1-af31-c3a3d788678e nic --mac 00:11:22:33:44:55
--model virtio
