Can't go get with go version 1.12

[Faeranne]

Attempting to go get github.com/monax/hoard/cmd/hoardresults in multiple import errors:

go/src/github.com/monax/hoard/server/server.go:9:2: code in directory /<redacted>/go/src/github.com/monax/hoard expects import "github.com/monax/hoard/v3"
go/src/github.com/monax/hoard/config/storage/filesystem.go:8:2: code in directory /<redacted>/go/src/github.com/monax/hoard/storage expects import "github.com/monax/hoard/v3/storage"

This is a brand new go install with $GOPATH set to $HOME/go which does exist.

We have switched to go modules. Currently there doesn't seem to be a massively user friendly way to get the old behaviour, but the following works:

GO111MODULE=on go get github.com/monax/hoard/cmd/hoard

See: golang/go#27653

Also our recommended way to get a release is from: https://github.com/monax/hoard/releases where we have cross-compiled binaries that contain the correct version metadata and link to our actual releases. In the future we may use also use build tags to enable specific storage backends selectively so that will further demerit go get installs.

As an aside: nice to hear someone else is using Hoard. Feel free to open issues or feature requests.
