Piotr Dulikowski ea25b29684 db/system_distributed_keyspace: add shares column and upgrade code
Add the "shares" column to the
system_distributed_keyspace.service_levels table, which is used by
legacy code.

Because this table is in a distributed and not local keyspace, adding
the column to an existing cluster during rolling upgrade requires a bit
of care. A callback is added to the workload prioritization cluster
feature which runs when the feature becomes enabled and adds the column
for all nodes in the cluster.
