Mehdi Abaakouk 1dcbd607df Deprecating transformers and pipeline partitioning
Theses features doesn't work well, rate-of-change metrics can still
wrongly be computed even with Pipeline partioning enabled. Also backend
like Gnocchi offers a better alternative to compute them.

This deprecates these two features, to be able to remove them in a couple
of releases.

deprecations:
- |
Usage of transformers in Ceilometer pipelines is deprecated. Transformers in Ceilometer
have never computed samples correctly when you have multiple workers. This functionality can
be done by the storage backend easily without all issues that Ceilometer has. For example, the
rating is already computed in Gnocchi today.
- |
Pipeline Partitioning is also deprecated. This was only useful to
workaround of some issues that tranformers has.
