Improve queue join messages

[Rdeisenroth]

This is where the interpolation options for the queue join messages are currently defined:

Rubot2/src/models/queues.ts

Lines 204 to 241 in b06fd7b

	public interpolateQueueString(this: DocumentType<Queue>, string: string, entry_resolvable?: string | QueueEntry | undefined): string | null {
	try {
	const replacements: StringReplacements = {
	"limit": this.limit,
	"name": this.name,
	"description": this.description,
	"eta": "null",
	"timeout": (this.disconnect_timeout ?? 0) / 1000,
	"total": this.entries.length,
	};
	if (entry_resolvable) {
	let entry: QueueEntry | null;
	if (typeof entry_resolvable === "string") {
	entry = this.getEntry(entry_resolvable);
	} else {
	entry = entry_resolvable;
	}
	if (entry && this.contains(entry.discord_id)) {
	const entryReplacements: StringReplacements = {
	"member_id": entry.discord_id,
	"user": `<@${entry.discord_id}>`,
	"pos": this.getPosition(entry.discord_id) + 1,
	"time_spent": (moment.duration(Date.now() - (+entry.joinedAt)) as unknown as { format: (arg0: string) => string; })
	.format("d[d ]h[h ]m[m ]s.S[s]"),
	};
	for (const [key, value] of Object.entries(entryReplacements)) {
	replacements[key] = value;
	}
	}
	}
	// Interpolate String
	return utils.general.interpolateString(string, replacements);
	} catch (error) {
	console.log(error);
	return null;
	}
	}

As you can see, we are missing interpolation options for active_coaches, closing_time and possibly more. Also it is currently not possible to set the message with just commands. You have to manually edit the db.

Furthermore, we should use QueueModel.interpolateQueueString() here

Actually the entire file could use some refactoring...
