The abstract base classes previously defined in 'collections' were moved
to 'collections.abc' in 3.3. The aliases will be removed in 3.10.
Preempt this change now with a simple find-replace:
$ ag -l 'collections.($TYPES)' | \
xargs sed -i 's/\(collections\)\.\($TYPES\)/\1.abc.\2/g'
Where $TYPES is the list of moved ABCs from [1].

Six is in use to help us to keep support for python 2.7.
Since the ussuri cycle we decide to remove the python 2.7
support so we can go ahead and also remove six usage from
the python code.
Review process and help
-----------------------
Removing six introduce a lot of changes and an huge amount of modified files
To simplify reviews we decided to split changes into several patches to avoid
painful reviews and avoid mistakes.
To review this patch you can use the six documentation [1] to obtain help and
understand choices.
Additional informations
-----------------------
Changes related to 'six.b(data)' [2]
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
six.b [2] encode the given datas in latin-1 in python3 so I did the same
things in this patch.
Latin-1 is equal to iso-8859-1 [3].
This encoding is the default encoding [4] of certain descriptive HTTP
headers.
I suggest to keep latin-1 for the moment and to move to another encoding
in a follow-up patch if needed to move to most powerful encoding (utf8).
HTML4 support utf8 charset and utf8 is the default charset for HTML5 [5].

Blueprint: support-conditions-function
Change the definitions of the Template.conditions() method to return a new
heat.engine.conditions.Conditions object. This class encapsulates the error
handling involved in looking up a condition, and lazily caches resolved
values so that conditions we never reference are not evaluated.
By raising ValueError instead of StackValidationFailed inside
Conditions.is_enabled(), we ensure that the user sees the full path to the
erroneous condition name if it appears inside the 'if' intrinsic function.
