This patch is used to add breaktrace option to monitor the latency
values while executing cyclictest test cases as a part of kvmfornfv
verify and daily jobs.

we need to be following defautl paramiko rules,
first use pkey, then key_filenames (autodetecting ~/.ssh/ keys),
then password
We have too much boilerplate redudant code everywhere, we need
to standardize on a factory function that takes a node dict.
Using Python3 ChainMap we can layer overrides and defaults.
VNF descriptors have to default key_filename, password to Python None.
The only way to do this is to omit key values if the variable is not
defined, this way the dict will not have the value and it will
default to Python None
Add python2 chainmap backport
Updated unittest mocking to use ssh.SSH.from_node

In CI when run tc070, there is a error: Failed executing command: 'free -s 1 -c 10'
Here it is the log:
Traceback (most recent call last):

RuntimeError: ('Failed executing command: ', 'free -s 1 -c 10',u"free: seconds argument `1' failed\n")
And it is a bug of free. the -c option should in front of -s, so change the position will solve
this problem.
Also it has another bug:
'KeyError', there no 'cached' keyword, so I change it to 'buff/cache'.

Porting to Python3 using Openstack guidelines:
https://wiki.openstack.org/wiki/Python3
This passes unittests on Python 3.5 and passes opnfv_smoke suite
Updates:
use six for urlparse and urlopen
fix exception.message attribute removal
run unittests on python3
use unitest.mock on python 3
fix open mock for vsperf
fix float division by using delta/eplison comparison
use unicode in StringIO
use plugin/sample_config.yaml relative path from test case
fixed apexlake unittests
upgraded to mock 2.0.0 to match python3 unittest.mock features
fixed flake8 issues
implement safe JSON decode with oslo_serialization.jsonutils.dump_as_bytes()
implement safe unicode encode/decode with oslo_utils.encodeutils
heat: convert pub key file from bytes to unicode
pkg_resources returns raw bytes, in python3
we have to decode this to utf-8 unicode
so JSON can encode it for heat template

requires https://gerrit.opnfv.org/gerrit/#/c/25183/
use new ssh method _put_file_shell to upload files.
We have to use _put_file_shell because we rely on ~/ path
expansions. Eventually we should move to remote absolute
paths so we can use sftp upload.
For ssh.execute() replace open() with context manager
context managers were invented partly to control
freeing resources. Opening files without closing
them will leak file descriptors.
The old standard method for closing files:
f = open('data.txt')
try:
data = f.read()
finally:
f.close()
was replaced with a context manager
with open('data.txt') as f:
data = f.read()

Video: https://youtu.be/OSGv2VnC0go?t=2522
Always use context managers for files
Update:
rebased now that _put_file_shell was merged

The logging methods do string interpolation themselves
From the reference:
https://docs.python.org/2/library/logging.html#logging.Logger.debug
Logger.debug(msg, *args, **kwargs)
Logs a message with level DEBUG on this logger. The msg is the message format string, and the args are the arguments which are merged into msg using the string formatting operator. (Note that this means that you can use keywords in the format string, together with a single dictionary argument.)
There are two keyword arguments in kwargs which are inspected: exc_info which, if it does not evaluate as false, causes exception information to be added to the logging message. If an exception tuple (in the format returned by sys.exc_info()) is provided, it is used; otherwise, sys.exc_info() is called to get the exception informatio
The reason logging does string interpolation itselfs is to implement deferred interpolation.
String interpolation involves evaluating arguments, so it can introduce significant computation. The logging module tries to be smart about deferring interpolation until the last possible moment.
The logging methods check isEnabledFor for the log level and won't interpolate if the level is not enabled.
https://github.com/python/cpython/blob/2.7/Lib/logging/__init__.py#L1178
def warning(self, msg, *args, **kwargs):
if self.isEnabledFor(WARNING):
self._log(WARNING, msg, args, **kwargs)
logging actually waits to interpolate the string in LogRecord.getMessage()
https://github.com/python/cpython/blob/2.7/Lib/logging/__init__.py#L328
if self.args:
msg = msg % self.args

In Heat Liberty release OS::Nova::Server will always use the user
pre-configured in the image (e.g. "fedora" for stock Fedora cloud
images, "ubuntu" for stock Ubuntu cloud images, "cloud-user" for
stock CentOS cloud images etc)

This scenario reads processor and system load statistics
and does not run any benchmark tests.
The scenario is intended to be run in parallell with
other scenarios in order to collect processor and system
load statistics.
System load is read from /proc/loadavg.
Processor usage stats is read using the 'mpstat' utility if
it has been installed on the host.
If 'mpstat' is not installed on the host processor usage stats
is read from /proc/stats.

Heat context code refactor to cater for the evolution of the
Yardstick framework.
Refactor runner_cfg host/target info handle, as specified at
https://etherpad.opnfv.org/p/yardstick_framework
step 4. Get general Context info (use Context.get).
Before this refactor host and target vm must have the same user name
and ssh key, that is not general enough for later extension.
test_case.yaml do NOT need to change.

Logging level should be specified using a command line flag -v or -d
when running yardstick, rather than hardcoded into source code. If the
message is to be displayed whenever yardstick is executed regardless
of the verbosity level, then the message should be logged to warning
or error levels, instead of debug.
