DRILL-4728: Add support for new metadata fetch APIs + Protobuf messages - GetCatalogsReq -> GetCatalogsResp - GetSchemasReq -> GetSchemasResp - GetTablesReq -> GetTablesResp - GetColumnsReq -> GetColumnsResp + Java Drill client changes + Server side changes to handle the metadata API calls - Provide a self contained `Runnable` implementation for each metadata API that process the requests and sends the response to client - In `UserWorker` override the `handle` method that takes the `ResponseSender` and send the response from the `handle` method instead of returning it. - Add a method for each new API to UserWorker to submit the metadata work. - Add a method `addNewWork(Runnable runnable)` to `WorkerBee` to submit a generic `Runnable` to `ExecutorService`. - Move out couple of methods from `QueryContext` into a separate interface `SchemaConfigInfoProvider` to enable instantiating Schema trees without the full `QueryContext` + RPC version is not yet updated. Will updated once all APIs are in master. @parthchandra Could you please review the patch?
