Packaging CI jobs should register in CR before start

[Dmitry Mescheryakov]

Right now, it does not happen and as a result it leaves wrong impression that CI is finished, while it is not. For example see
https://review.fuel-infra.org/#/c/13649/

Example of good behaviour: mos-infra-ci leaves the following comment on start
------------------------------------------------
Patch Set 1: -Verified
Build started (check pipeline) http://status.mosi.mirantis.net/zuul/
gate-oslo.messaging-pep8 STARTED
gate-oslo.messaging-python27 STARTED
------------------------------------------------
As a result, gate-oslo.messaging-pep8 and gate-oslo.messaging-python27 jobs appear in CI table when they are running and a user understands that CI is not finished yet.

The same should be done for all other CI jobs, specifically for 8.0-pkg-pipeline-ubuntu and 8.0-pkg-pipeline-centos

Another bad example is comment from Pkgs Jenkins:
------------------------------------------------
Patch Set 1: -Verified
Starting pkg-build-mos jobs. http://packaging-ci-gate.infra.mirantis.net/
------------------------------------------------
It is bad because the comment it done in wrong format and as a result, it does not make 'pkg-build-mos' appear in the CI table

I tried patch ('Report jobs that will run immediately' by Dmitry Teselkin) used by Infa CI - it not works with new Zuul (Infra uses 2.0.1, Packaging uses 2.1.0):

2015-11-11 09:25:04,595 ERROR zuul.IndependentPipelineManager: Exception while reporting start:
Traceback (most recent call last):
  File "/usr/local/lib/python2.7/dist-packages/zuul/scheduler.py", line 1096, in reportStart
    for job in self.pipeline.getJobs(change):
  File "/usr/local/lib/python2.7/dist-packages/zuul/model.py", line 123, in getJobs
    if not item.live:
AttributeError: 'Change' object has no attribute 'live'

So this feature needs more Zuul investigation.
