RFR 8146803: Update to the sharding API

[Lance Andersen]

Hi,

Please review the attached webrev which addresses some changes we needed to make to the sharding API.  The CCC has been approved.  The webrev can be found at: http://cr.openjdk.java.net/~lancea/8146803/webrev.00/


Here is a brief description of the changes

-ConnectionPooledDataSource needed to add a PooledConnectionBuilder as like DataSource and XADataSource this will create a physical connection and the ShardingKey will be needed
- PooledConnectionBuilder - is used to create a PooledConnection ->physical connection so it needed access to the ShardingKey
- CommonDataSource added createShardingKeyBuilder making it available to DataSource, XADataSource and ConnectionPoolDatasource. 
- DataSource/XADataSource removed createShardingKeyBuilder as it now is on CommonDataSource which they both extend
- XAConnection removed the setShardingKey methods.  Having the methods on Connection should be adequate as the ShardingKey is needed for the Connection which they already exist on.
-XAConnectionBuilder had a minor typo in the javadoc
