Go modules v2 compatibility

[invidian]

Short summary

As latest released version at the time of writing is v2.2.0, which do not include v2 subdirectory, currently running go get -u github.com/tommy-muehle/go-mnd/cmd/mnd pulls latest v1 version (v1.3.0), as it is by design with Go modules.

This may lead to confusion, as many users may user older version, without access to new features.

Steps to reproduce the behavior

Run go get -u github.com/tommy-muehle/go-mnd/cmd/mnd on a fresh system.

Go version (output of 'go version')

go version go1.15.3 linux/amd64

Operating system / Environment

$ cat /etc/os-release
NAME="Arch Linux"
PRETTY_NAME="Arch Linux"
ID=arch
BUILD_ID=rolling
ANSI_COLOR="38;2;23;147;209"

Expected behavior

Documented go get -u github.com/tommy-muehle/go-mnd/cmd/mnd and all imports should be changed to github.com/tommy-muehle/go-mnd/v2/cmd/mnd, including go.mod, so latest version is pulled.

This can be used as an example to follow: kubernetes/klog@2bed4d0#diff-33ef32bf6c23acb95f5902d7097b7a1d5128ca061167ec0716715b0b9eeaa5f6
