Returns a stream consisting of the entries of this stream, additionally
performing the provided action on each entry key-value pair as entries
are consumed from the resulting stream.

<p>
This is an <a href="package-summary.html#StreamOps">intermediate</a>
operation.

<p>
For parallel stream pipelines, the action may be called at whatever time
and in whatever thread the element is made available by the upstream
operation. If the action modifies shared state, it is responsible for
providing the required synchronization.

@param action a non-interfering action to perform on the keys and values
of the entries as they are consumed from the stream
@return the new stream
