[Feature Request] Ability to "clone" bot (AKA: manage multiple tokens)

[steph9009]

This become extremely helpful to deploy several instances of the same bot (e.g. a self-hosted).
Each instance is like a new virtual bot which can fetch different feeds to different users (or channels/groups).
It's very useful, for example, to split different arguments and that's not always doable creating new channels, because there's a maximum limit of 10 channels ad personam on Telegram.

This is taken from other bots like GroupHelp and Manybot

Official guide to clone GroupHelp: https://t.me/HowToClone

Example procedure to clone Manybot:

Manybot
1⃣ Go to @BotFather. Press his name to do that and then press 'Send Messege' if it's needed.
2⃣ Create a new bot with him. To do this use the 'newbot' command inside @BotFather.
3⃣ Copy the API token that @BotFather will give you.
4⃣ Come back to @Manybot and send the copied API token here.

Facultative steps: you can directly send the token {

Manybot
