sharder: support rows_per_shard in config file

Code Issues Proposed changes

Make rows_per_shard an option that can be configured
in the [container-sharder] section of a config file.
For auto-sharding, this option was previously hard-coded to
shard_container_threshold // 2.
The swift-manage-shard-ranges command line tool already supported
rows_per_shard on the command line and will now also load it from a
config file if specified. Any value given on the command line takes
precedence over any value found in a config file.
