[HDFS-8943] Read apis in ByteRangeInputStream does not read all the bytes specified when chunked transfer-encoding is used in the server

Description

With the default Webhdfs server implementation the read apis in ByteRangeInputStream work as expected reading the correct number of bytes for these apis :

public int read(byte b[], int off, int len)

public int read(long position, byte[] buffer, int offset, int length)

But when a custom Webhdfs server implementation is plugged in which uses chunked Transfer-encoding, these apis read only the first chunk. Simple fix would be to loop and read till bytes specified similar to readfully()
