  The commit "Remove metadata from token provider" with ID (I4b37289c06df2012ed4473227df5c309440af162) broke the ec2 v2 controller. The call to _authenticate expects 5 parameters in v2 and 4 in v3 giving that exception.

  Also the removal of the issue_v2_token token provider method did not
  have effect in the ec2 v2 controller that it is still using it.

  The bug was introduced in Ocata and it is still there in the master
  branch
