DIRAC v6r17

##DMS

Important change: The values for registration and third party protocols have to be moved from Resources to Operation, and new lists are needed :

DataManagement/RegistrationProtocols # Comes from Resources/FileCatalogs
DataManagement/ThirdPartyProtocols # Comes from Resources/FileCatalogs
DataManagement/AccessProtocols
DataManagement/WriteProtocols

For the extensions, the Resource Helpers getRegistrationProtocols and getThirdPartyProtocols are replaced with methods (same name) in the DMSHelpers class

These lists can be overwritten at the level of a StorageElement, and they should be if it is a special case. For example, for LHCb, the OnlineRunDB storageElements needs to have "http" as WriteProtocols

##DMS

There is a need to change the schema of the table SpaceTokenOccupancyCache (ResourceManagementDB). Column Endpoint must be set to varchar(128)
