Add Functionality needed to appropriately handle resources from rdsys

• Currently rdsys' gone resources do not indicate blockages but improperly functioning bridges

• gone resources should not be handled in a way that may punish users or require users to migrate

• hot spare individual bridges may be useful to allocate to a bucket with resources that have been removed due to a non-blockage

• Ensure that the bridge table can stay in-sync with rdsys. This may require added functionality to add associated repos
