Allow threads to be set at the bots text channel

### Is your feature request related to a problem? Please describe.

Unable to set bot text channel to a thread. Threads would allow a concise place for the bot commands alongside a text channel.

### What is your ideal solution to the problem?

Have the bot check if there is a valid thread in the tc for the guild. If not it creates a new thread and caches the id. otherwise acts like a normal tc.

### How would this feature be used?

either add a use threads setting which will have the bot make a thread in the channel instead of using the text channel directly or, add a set thread option which will make the bot message in that thread instead.

- [X] I have checked [the documentation](https://jmusicbot.com/) to make sure this feature doesn't already exist
- [X] I have searched for [similar feature requests](https://github.com/jagrosh/MusicBot/labels/enhancement)
- [X] I have confirmed that my requests is **not** on the [list of things that will not be added](https://jmusicbot.com/things-that-wont-be-added)
- [X] I am running the latest version of the bot: 

No files, tests, or entry points are named. Start by locating the bot text-channel configuration and the Discord channel-message handling, then review how the project uses its Discord library. The scope still needs a decision between automatic thread creation and an explicitly configured thread before completion can be defined.
