Collect shard sizes for closed indices

Today the `InternalClusterInfoService` collects information on the sizes of
shards of open indices, but does not consider closed indices. This means that
shards of closed indices are treated as having zero size when they are being
allocated. This commit fixes this, obtaining the sizes of all shards.
