This is in preparation for having other "command changing things" like
redirecting to file and maybe variable substitutions in the arguments.
"On the way" added a
RUNNING "some_command" "--some_flag" "some_value"
to the output encapsulator so that if we run multiple commands, we know what
command was called where.

Move the shell output encapsulation so that we don't double-wrap on a
premature exit.

Since the ConsoleReader now controls the display of the prompt, there is no
longer any way for an external program interacting with the nomulus shell to
recognize when the last command issued has been completed.
To remedy this, we introduce an "--encapsulate_output" flag, which causes
standard output and standard error to be wrapped in a class that precedes
all normal lines of output with a prefix ("out: " or "err: ", accordingly)
and allows the command processor to insert a "SUCCESS" or "FAILURE"
line (with no special prefix) after completing the processing of a
command.

We don't want people to accidentally run commands on prod thinking they were on
Alpha / Sandbox.
To do that - we add 2 safeguards:
1) when on prod, the shell has a strong RED "PRODUCTION" in the commandline, while on alpha/sandbox it's green.
2) if a prod shell is idle for > 1h, it exits. So don't accidentally use a prod shell from a long time ago.

After writing a flag on the shell, pressing "tab" will print out the
documentation for that flag.

Even though you couldn't run a "shell" inside a "shell", the completion still
assumed you could :(
On the way - fixing error on empty lines: when you just press "enter", the shell should ignore it rather than try to run it as a command (and getting an error, obviously)

Using the jline open-source library.
We save the history between invocations to ~/.nomulus_history
We add some simple completions:
- first argument completes to command name
- all other arguments complete to the command parameters, or filename

Add the "shell" command which lets you run multiple other command in a single
session, sparing you the initialization costs for all but the first of them.
