These are failing because of this patch on tap-as-a-service 
https://opendev.org/x/tap-as-a-service/commit/8332a396b1b046eb370c0cb377d836d0c6b6d6ca

Really have no idea how this works, does anyone use tap-as-a-service with midonet and can help me fix it, else I’m wondering if we disable tests for taas and make it an unsupported feature for now.
