[sdk][release][requirements] FFE requested for openstacksdk

Heya,

We’d like to cut an 0.35.1 bugfix release as part of train to grab https://review.opendev.org/#/c/680649/ and https://review.opendev.org/#/c/682454/. The first is landed and is in support of the Ironic Nova driver. The second is making its way through the gate right now and is in support of OSC v4.

Thanks! Monty
