Add debug_reconnects to socketmode client

[AyumuKasuga]

Description

Hello Team,
thanks for this beautiful project! It would be nice to have an option to add &debug_reconnects=true to the WebSocket URL. Here is how it described in the docs:

One helpful trick: you can append &debug_reconnects=true to your WebSocket URL when you connect to it in order to make the connection time significantly shorter (360 seconds). That way, you can test and debug reconnects without waiting around.

What do you think?

(Optional) Slack's documentation

https://api.slack.com/apis/socket-mode

This seems to be for debugging purposes only (as the name implies) so I might just use the Client debug as a proxy for when to enable this in socket mode.

Something along the lines of

if api.debug {
    // Append &debug_reconnects=true
}
