    Catch APIException exceptions raised by Mistral

    In the change to keystone sessions and Mistral client 3.2.0 the
    exception raised when fetching an environment that doesn't exist
    changed. This adds the new exception but continues to catch the previous
    one.

and in that one: "Likely a dupe of https://bugs.launchpad.net/tripleo/+bug/1748751"

There were two issues, in mistralclient, fixed in 3.3.0 and instack-undercloud which was uncovered after fixing first one.
