Description

Currently all the WAL Providers acceptable to hbase are specified in Providers enum of WALFactory.
This restricts the ability for custom Meta WAL Provider to default to the custom WAL Provider which is supplied by class name.

This issue fixes the bug by allowing the specification of new WAL Provider class name using the config "hbase.wal.provider".
