Add support for getMyCommands/setMyCommands #13
Description
Currently, bot developers need to talk to @Botfather in order to update the list of commands their bots understand. However, a more elegant solution could be provided if the bot was able to reflect its understood commands itself and report any changes to the Bot API.
This would involve designing stronger command management in the framework - currently, clients are responsible themselves for dispatching commands. Also, there might be some synchronization issues - when should updates be sent to the server? With a constant frequency? By monitoring changes to a certain method? What should happen if the bot is suddenly served from a different image/code base?
