Define URI Prefix for SKA Data

This work will look at defining a common URI prefix to identify data stored in the SKA DataLake. At the moment, data identifiers for data in the SKA DataLake are based on the Rucio identifiers, without a distinguishing prefix. This makes it hard to distinguish between a URI for data in SKA and data in another platform. Services and users have to rely on context to understand which platform the data is in.

By addressing this before further implementation of SRCNet0.1 we can reduce the complexity of the roll out. (Though not explicitly required for v0.1).
The later we leave this the more it will cost to adapt existing software and services which have been developed without expecting a URI prefix.

AC1: The first stage of this work will define the best form for the prefix and identify what changes are needed to the existing code base to support this.
AC2: The results will be reported back to the project team for evaluation. (? who?, which project?)
AC3: If it is decided to adopt this proposal, the second stage will implement the required changes in the SRCNet code base and manage the roll out.
