> Add support for Kerberos and Basic Auth in webhdfs

> webhdfs's HTTP operation like get ( GetOpParam.java) operation and other HTTP
> operation has 'requireAuth' set to false and expected to work with Delegation
> token only. However, when working with webhdfs over Apache Knox, delegation
> token authentication is not supported, we should support Kerberos
> authentication (SPNEGO) or Basic authentication for WebHdfsFileSystem if user
> turns on a configuration.
> Further webhdfs (WebHDFSFileSystem.java) is calling 'public URLConnection
> openConnection(URL url)' and providing no way to use the kerberos
> authentication, if configured.
> Even after setting the UserGroupInformation with user name and keytab,
> openConnection is not using the keytab for authentication.
> Also WebHdfsFileSystem doesn't provide any support for HTTP BASIC
> authentication (username/password). Provide support to read the password via
> environment variable.
