JNetCLI shall become a REPL tool

[masesdevelopers]

Is your feature request related to a problem? Please describe.
There is no CLI to interact with JNet. The JNetCLI tool can be used to run Java classes or execute code.

Describe the solution you'd like
The JNetCLI shall work in, at least, two different ways:

• Interactive mode: the user launches the program and a REPL interface will be available; inserting code an user can request JVM objects and interact, side-by-side, with .NET objects;
• Run mode: the user requests to launch a JVM class (the one with a main) with arguments in command-line; this is the same behavior of java command-line executable.

An extra mode to be considered is:

• Script mode: the user requests to launch a C# Script (mix of .NET and JVM objects) which executes and then exit.
