Acquire NSB specific data from Heat.

First we add mac_address, subnet_cidr to Heat template outputs
Then we convert those into a form for NSB and add vld_id.

NSB also requires PCI Bus ID, kernel driver
and dpdk_port_num.  We get this by ssh-ing
into instance and dumping sysfs

We also need to fix allow for ssh key auth,
and implement relative path file loading
so NSB can find all its YAML files

JIRA: YARDSTICK-580

Change history:

don't hide heat create tracebacks we need tracebacks for debug

vnf_generic: add task_path to scenario so we can load relative paths

    for vnf_generic we want to be able to load yaml relative to the
    task path

    For example:
      traffic_profile: ../../traffic_profiles/fixed.yaml
      topology: ping_tg_topology.yaml  # TODO: look in relative path where the tc.yaml is found

    These need to be relative to samples/vnf_samples/nsut/ping/tc_ping_heat_context.yaml

    Add a scenario["task_path"] entry

heat: log actual exception

vnf_generic: replace list with set and iterate over values()

    some general refactors to remove redundact lookups and
    type conversions

heat: provide mac_address, device_id and network_id from outputs

    We may need more information to dynamically
    determine test topology.

    Towards this end return more info in the heat template.
    We can return mac_address, device_id and network_id.

    Once we have this info we can add it to the context_cfg
    as an interfaces dict.

add sample vnf ping multi-network test
    this test requires 3 network, one for mgmt
    and the other two for NSB traffic tests
    We have to make sure we don't use DPDK
    on mgmt interface because DPDK unbinds
    the driver

heat: convert networks to OrderedDict

    so we can lookups networks as well as
    iterate over them in consisitent order

heat: and vld_id to networks for vnf_generic

    vnf_generic uses vld_id  Virtual Link Descriptor ID
    to identify interfaces

    Add the key to the networks dict
    and store in Networks object

implement relative path file loading in vnf_generic

    in multiple places we need to load a file
    relative to the task path, so add
    open_relative_file_path

    and modify load_vnf_model to include the scenario_cfg
    parameter so we have access to task_path

DRAFT: heat timeout support

    Heat stack in CI job failed due to some Nova issue.

    But then apparently yardstick kept running and took 180mins to timeout

    https://build.opnfv.org/ci/view/bottlenecks/job/bottlenecks-compass-posca_stress_ping-baremetal-daily-master/16/console

    We can add a Heat create timeout and fail faster if there is an error.

    The question is how long should we wait for a Heat stack to deploy.  We
    can set a default and allow override in the heat context config, if
    users make complicated stacks

heat: get netmask and gateway from heat outputs

    we have do some tricky business with finding
    the subnet cidr and converting it into netmask

vnf_generic: get vpci, driver and dpdk_port_num

    use a big old find command to dump all the sysfs
    netdev info nicely.  This was re-used from autotest FCoE tests.

    r"""find /sys/devices/pci* -type d -name net -exec sh -c '{ grep -sH ^ \
    +$1/ifindex $1/address $1/operstate $1/device/vendor $1/device/device \
    +$1/device/subsystem_vendor $1/device/subsystem_device ; \
    +printf "%s/driver:" $1 ; basename $(readlink -s $1/device/driver); } \
    +' sh  \{\}/* \;

    This finds all PCI devices that are network devices, then
    dumps all the relevant info using /bin/sh.

    Then we parse this into a 'netdevs' dict inside the node_dict
    and also convert into VNF fields we need.

vnf_generic: set node name for kpis

    node is a dict, so we have to use node_name

vnfdgen:  we CANNOT use TaskTemplate.render

    because it does not allow for missing variables, we need to allow
    password for key_filename to be undefined

remove default ssh password hack, once rendering is fixed

add new example tc_external_ping_heat_context
