features:
- The RestClient (in tempest.lib.common.rest_client) now supports POSTing
and PUTing data with chunked transfer encoding. Just pass an `iterable`
object as the `body` argument and set the `chunked` argument to `True`.
- A new generator called `chunkify` is added in
tempest.lib.common.utils.data_utils that yields fixed-size chunks (slices)
from a Python sequence.
