Open Stack

For the sake of completeness: The eventlet package version 0.18.1
seems to be disappeared from the PyPi servers, which is a bad thing,
as we use that version in the "upper-constraints.txt" of the
requirements project. There is patch [1] in the queue which solves that.
Until this is merged, there is a change that our CI (and your third-party
CI) will break after the locally cached version in the CI vanishes.
