Go introduced a 'native' way to wrap errors back in v1.13. At that point we were
already using github.com/pkg/errors to 'wrap' errors with context, and we never
got around to migrating. In addition to pure inertia, I've personally avoided
making the switch because I prefer the github.com/pkg/errors API. Specifically I
like that errors.Wrap handles the "outer context: inner context" error format
that Go uses by convention, and that errors.Wrap will return nil when passed a
nil error.
Given that github.com/pkg/errors has long been in maintenance mode, and is (per
https://github.com/pkg/errors/issues/245) no longer used by its original author
now seems as good a time as any to migrate. This commit attempts to ease that
migration for the Crossplane project - and to retain the nice API - by adding a
package that acts as a small github.com/pkg/errors style shim layer around the
stdlib pkg/errors (and friends, like fmt.Errorf).
