> FileChecksum should provide getChecksumOpt method

> o.a.h.f.FileSystem has several methods which accepts directly or indirectly a
> ChecksumOpt parameter to configure checksum options, but there's no generic
> way of querying checksum options used for a given file.
> MD5MD5CRC32FileChecksum used by DFSClient has a getChecksumOpt() but since
> not just DistributedFileSystem is accepting a ChecksumOpt argument, but any
> FileSystem subclass (although only DistributedFileSystem implements a
> specific behaviour), I suggest to make getChecksumOpt an abstract method of
> FileChecksum. This could be used by tools like DistCp to replicate checksum
> options for example.
