JDK-8199912 - jshell /open URL

[Michal Vala]

Hi,
I've been implementing jshell function to open scripts from url - JDK-8199912.

Here's the rough working implementation: 
https://michalvala.fedorapeople.org/webrevs/JDK-8199912/webrev.00/

Few questions:

1] Is this requirement still valid?
2] Is dependency on java.net.http module ok?
3] Is there any better way how to detect http URL? This is ugly, but I haven't 
find any better example inside jdk.
4] Any better way how to handle http response status?
