Porting to use telebot.v2

[lovung]

I am doing upgrade telebot from v1 to v2 at https://github.com/vu-long/alertmanager-bot/tree/using_telebot_v2 but it runs with any response. Can you help me?

[metalmatze]

I haven't looked at the differences between v1 and v2. But if you want you're welcome to create a PR to only update the dependency and then we can work on that.

@metalmatze #45 here please. I just took some hours. Maybe I will come back to work on that in next week.

Issue (without using dep)

go get -u github.com/metalmatze/alertmanager-bot
cd $GOPATH/src/github.com/metalmatze/alertmanager-bot
go get -v -u ./...
go build ./...

Output:

Yes, you need to enable Go modules at the moment. Please read this section on how to do that:
https://github.com/golang/go/wiki/Modules#how-to-install-and-activate-module-support

TL;DR
export GO111MODULE=on and then run go build -v ./cmd/alertmanager-bot again.

It's OK. Maybe we need to change the README.md for others.

Today I finally put some work into upgrading the telebot library to v2. It turns out it only got worse from its API calls and I actually prefer not to upgrade to it.
Right now, I'm unsure about the way forward, but we'll figure something out eventually.
