[LIVY-409] Livy shell UX improvements
I'm not sure how large of an audience the livy-shell has, but I've come to
use it quite a bit in my testing/use of Livy and added a few small improvements
that have made it a bit easier to use for me (and may help others):
* Replaced the use of httplib with requests to fix dropped connection
issues (and a few other robustness issues).
* Added some context to the REPL prompt, by including the session `kind`
and ID.
* Ignore `SIGINT` signal so that users can type `CTRL-C` to cancel out a
command.
I know the use of `requests` is pretty ubiquitous but I included
`livy-shell-requirements.txt` just in case 1) someone doesn't have it installed
or 2) more dependencies are added down the road.

> Improve User Experience in livy-shell

> Key: LIVY-409
> URL: https://issues.apache.org/jira/browse/LIVY-409
> Project: Livy
> Issue Type: Improvement
> Reporter: Eric Perry
> Priority: Minor
>
> The livy-shell is useful in testing and evaluation of the use of Livy, but
> has a few minor UX issues that could be fixed without many changes:
> # The use of httplib and a single connection can cause problems in
> environments where network reliability is low.
> # The shell prompt does not include any contextual information, which may be
> helpful when a user has multiple shells running.
> # There isn't an easy way to cancel the current command other than deleting
> all the text on the prompt as SIGINT breaks out of the REPL and causes the
> session to be deleted.
