History
Ernest Zaslavsky b9e1dcc0fe s3: distribute connection pool proportionally across scheduling groups 
The S3 client creates a separate HTTP connection pool per scheduling
group. Previously, the pool size was computed per-group using a
per-share multiplier (connections = shares * multiplier), which did
not account for the total number of groups sharing the shard's
connection budget.

Replace the per-share multiplier with a per-shard connection budget:
the new object_storage_connections_per_shard config option (default
100) specifies the total number of connections available on each
shard. When a new scheduling group's client is created, connections
are distributed proportionally across all groups based on their
shares (connections = budget * group_shares / total_shares), and
existing groups are rebalanced via set_maximum_connections.

When the endpoint_config has an explicit max_connections override,
it is used directly without proportional distribution.
