When our go.mod file was introduced in commit 114e85c2002091eb415040923d872f8e4a4bc636 in PR #3208, the module path chosen did not include a trailing /v2 component. However, the Go modules specification now advises that module paths must have a "major version suffix" which matches the release version. We therefore add a /v2 suffix to our module path and all its instances in import paths. See also https://golang.org/ref/mod#major-version-suffixes for details regarding the Go module system's major version suffix rule.
