osd: EC Optimizations: Add shard_id_sets for backfill_target and ...
acting_recovery_backfill
Optimized EC code uses shard_id_sets as a convinient and fast way of
representing sets of shards. Peering calculates a backfill_target set
and an active_recovery_backfill set as a map of pg_shard_ids during
peering and these are then used while processing I/O requests.
Modify peering so that it initializes a shard_id_set version of
these two sets and makes these available to ECBackend code.
