The version of oslo.utils not matched between requirements.txt and code

[kobayashi]

After installing ceilometer agents, they cannot get resources.
At this time, I configured environment by devstack. The branch is origin/stable/kilo.

Heres are errors at the periodic discovering task.

edit the code 'self.last_run = timeutils.utcnow(True)' with 'self.last_run = timeutils.utcnow()'

I think this error is caused by that lib:'oslo.utils' version does not match.
This version limit: 'oslo.utils!=1.4.1,<1.5.0,>=1.4.0 # Apache-2.0' at requirements.txt of ceilometer project,
the function: utcnow has no arguments at limited versions.
So you would update version of oslo.utils by commands:
    sudo pip install oslo.utils==1.6.0

    Fix arguments error at call timeutils.utcnow

    The function: timeutils.utcnow at oslo.utils which libary has limited
    versions: !=1.4.1,<1.5.0,>=1.4.0, it has no arguments. But call at
    compute/discovery.py passing a argument, it will throw TypeError.
