Upgrade package versions and Upgarde to go 1.21

[Alan-MQ]

in order to upgrade to go 21, we just modify go.mod at the second line to go 1.21?
but actually I don't have a clue about how we upgrade package versions. for all packages? including pkg/ folder? that could cause some compatiable problem right?

let me try this one for now

Yes, just change the version in go.mod in each service and pkg module, also for GitHub action.
Yes it is fine, maybe something like go get -u -t -d -v ./... for each service.
After upgrading, the unit and integration tests should be pass as well.
