Description

As we move DFSClient (see HDFS-8053) and DistributedFileSystem (see HDFS-8740) from hadoop-hdfs to hadoop-hdfs-client, we need to move the client side config keys from DFSConfigKeys to HdfsClientConfigKeys in advance.

This jiras tracks the effort of moving all client related config keys, which are used by DFSClient and DistributedFileSystem, from hadoop-hdfs to hadoop-hdfs-client module.

We'd better mark these keys in DFSConfigKeys as @Deprecated for a while before totally deleting them, in case we break dependent code without being aware of it.
