Issue:
list_replicas with metalink should resolve all schemes, if no schemes are given
Motivation
----------
Currently the schemes have to be given explicitly. However, if no schemes are given all schemes should be replied, not only the top-priority one.

Historical view for used space by account and RSE
Motivation
----------

One needs a view to monitor the evolution of used space by account for a given or a set of RSEs.
