- More errors will be logged to the console with clearer messages when something goes wrong
- Downloading the Lavalink Jar will abort after 5 failed attempts. The connect task will also abort if an unhandled exception occurs whilst downloading or connecting to Lavalink. After this occurs, instead of responding "Connection to Lavalink has not yet been established" to commands, the bot will respond "Connection to Lavalink has failed". This has no effect on other commands which don't involve connecting to Lavalink (e.g. settings commands).
- Logs this message when Lavalink jar is successfully downloaded: `Successfully downloaded Lavalink.jar (<x> bytes written)`
- Uses [`tqdm`](https://github.com/tqdm/tqdm/) to display a progress bar whilst downloading Lavalink.jar.

* Refactor internal Lavalink server management
Killing many birds with one stone here.
- Made server manager into class-based API with two public methods: `start()` and `shutdown()`. Must be re-instantiated each time it is restarted.
- Using V3 universal Lavalink.jar hosted on Cog-Creators/Lavalink-Jars repository.
- Uses output of `java -jar Lavalink.jar --version` to check if a new jar needs to be downloaded.
- `ServerManager.start()` won't return until server is ready, i.e. when "Started Launcher in X seconds" message is printed to STDOUT.
- `shlex.quote()` is used so spaces in path to Lavalink.jar don't cause issues.
- Enabling external Lavalink will cause internal server to be terminated.
- Disabling internal Lavalink will no longer reset settings in config - instead, hard-coded values will be used when connecting to an internal server.
- Internal server will now run both WS and REST servers on port 2333, meaning one less port will need to be taken up.
- Now using `asyncio.subprocess` module so waiting on and reading from subprocesses can be done asynchronously.

* Don't use shlex.quote on Windows

* Don't use shlex.quote at all
I misread a note in the python docs and assumed it was best to use it. Turns out the note only applies to `asyncio.create_subprocess_shell`.

* Missed the port on the rebase
* Ignore invalid architectures and inform users when commands are used.
* Style fix
Also:
- restart and reconnect if connection settings change
- shutdown and restart if not configured to use external
- show a message in [p]play et al. when the connection hasn't been made
- move the JAR download to manager so audio.py can access it
- only start if no process exists
- bump red-lavalink to 0.2.3
Resolves#2306

- Update to red-lavalink v0.2.0 (blocked by Cog-Creators/Red-Lavalink#41)
- Force lavalink to use TLSv1.2 on java 11+ (blocked by #2270)
I would add equalizer support, but there's no way to know the full
Lavalink version and thus whether it's supported ahead of time.
* regex extension on java -version
* make it a non capturing group
* alphanumeric matching
* Match specification: Style, line length
* Update manager.py
Using the OpenJDK 11 from java.net on Ubuntu 18 reports "11" as the version, which failed the Java version check on loading audio on a new instance. This change will return "11 0" as the version, passing the check, instead of just "11".
