Surce Keystone creds explicitly from $PWD; use the 'member' role

Two small changes:

  - Source keystone admin explicitly from PWD: source
    $PWD/keystonerc_admin instead of source keystonerc_admin
  - Use the role _member_ instead of 'user' when assigning a
    role to the user

Thanks to Luigi Toscano for testing and reporting this.
