- Merge "constants: cache YAML config values"

don't reparse the yardstick.yaml file each

Use pkg_resources.resource_filename
to lookup the path of yardstick tests, intsead of using __file__
pkg_resources is slightly more proper than __file__
at least for packages

* Update docs/submodules/yardstick from branch 'master'
- Bugfix: remove ping package for it is GPL license
JIRA: YARDSTICK-777
In migrate test case, we use ping to count downtime.
But ping package is GPL license, so we need remove it.
Since ping command tool can not set timeout less then 1 second, and the
downtime is less then 1 second, so we need find another package to replace.
For now, I find most ping tool is GPL license, so maybe later we need to
implement ping ourselves.
And the migrate case can not calculate downtime unless user install ping
themselves.

- Bugfix: port_security_enabled issue
JIRA: YARDSTICK-765
When port_security_enabled is not set, VMs are assigned with security group 'default'.
When using 'default' security group, all egress traffic and intercommunication in the
default group are allowed and all ingress from outside of the default group is dropped
by default (in the default security group). This causes yardstick cannot ssh into VMs.
If port_security_enabled is not set, we should still add the security group that created
by yardstick to the VMs.

- Merge "Bugfix: yardstick always report 'PASS' to DB"
- Bugfix: yardstick always report 'PASS' to DB
JIRA: YARDSTICK-768
Now yardstick will not stop if test case failed,
so that we can run the rest test case in the suite.
CI judge task status by the cmd return code. In this way,
the 'yardstick task start' cmd will always return 0.
So we will always report 'PASS' to DB.
In this patch I add a judgement in cmd, if the status is not 'PASS', we
will raise a RuntimeError.

* Update docs/submodules/yardstick from branch 'master'
- Merge "support more parameters in iperf3 testcase"
- support more parameters in iperf3 testcase
JIRA: YARDSTICK-755
The parameters that iperf3 testcase support now maybe insufficient in some usecase.
The test case should support parameters such as: windows size and length of buffer.
This work is about adding more parameters that can be specified in options section in the YAML file.

* Update docs/submodules/yardstick from branch 'master'
- Merge "yardstick env influxdb/grafana cmd support centos"
- yardstick env influxdb/grafana cmd support centos
JIRA: YARDSTICK-714
Currently yardstick env influxdb/grafana command do not support centos.
Because we use the gateway ip to get the service of influxdb and grafana.
But in centos, we can not access influxdb/grafana service via gateway ip.
In this patch, I use docker inspect to get the ip of influxdb and grafana.
So these command can support centos.

* Update docs/submodules/yardstick from branch 'master'
- Merge "Add multiqueue support"
- Add multiqueue support
Problem:
Neither OVS nor SRIOV multi-queue is not supported. Guest VM lacks tuning to reach high throughput.
Solution:
(1) Build SRIOV multi-queue capable guest image by recompiling the igxbevf driver (make CFLAGS_EXTRA=-DIXGBE_ENABLE_VF_MQ install).
(2) Change pktgen to send on multiple queues.
(3) Add tuning in guest VM (Disable irqbalance and setup vNIC interrupt affinity to vCPUs)
Update 1: Takes care comments plus adds unit test cases
Update 2: Jenkins reports code coverage 81%, local reports 96%, add more unit test cases
Update 3: Manually rebased to adapt to SSH.from_node()
Update 4: Takes care comments for vnic_type, vnic_name
