Hi Nova Developers.

When the API microversion is bumped,
patches are required not only in nova side but also in python-novaclient  
side.

But, after the nova patches were merged,
the python-novaclient patches were sometimes not submitted for a while.

The patch in python-novaclient is necessary to submit a patch for a  
subsequent microversion.
For example, the patch for microversion 2.55 should be merged
after the patch for microversion 2.54 is merged.
There is a dependency between them.

So I'm proposing an amendment to the code review guide [1].
The code review guide should be changed as follows:

-----------------------------------------------------------------------------------------
A new patch for the microversion API change in python-novaclient side  
should be submitted
*before the microversion change in Nova is merged*.
-----------------------------------------------------------------------------------------
