> 1. Move irrelevant parts out of TestAsyncDFSRename
> 2. Limit of max async calls(i.e. ipc.client.async.calls.max) is set and 
> cached in ipc.Client. Client instances are cached based on SocketFactory. In 
> order to test different cases in various limits, every test (e.g. 
> TestAsyncDFSRename and TestAsyncDFS) creates separate instance of 
> MiniDFSCluster and that of AsyncDistributedFileSystem hence. This is not 
> efficient in that tests may take long time to bootstrap MiniDFSClusters. It's 
> even worse if cluster needs to restart in the middle. This proposes to do 
> refactoring to use shared instance of AsyncDistributedFileSystem for speedup.
