Reads the contents of {@code inputStream} into a HashMap. Each key-value pair in the input will result in an
entry in the map.
<p/>
The specified stream remains open after this method returns.

@param inputStream a stream with line-based, key-value pairs.
@param charset     the name of a supported {@link java.nio.charset.Charset charset}.
@return a HashMap initialized from the stream.
@throws java.io.IOException if an I/O error occurs
