Supervisor should go to Error when TCDS cannot configure
Description
Since 6285225f, the TCDS applications will return a SOAP fault if the lease is owned by another requestor. This is a sane behavior, but the error is ignored by the GEM Supervisor; it will stay in the Configuring
state forever.
Instead, the GEM Supervisor should go to Error if the TCDS cannot be configured, whatever the reason is.
Possible fixes
Fix #170 and react accordingly on SOAP faults.
