Update to Collector v0.28.0 (#49)

* Update to Collector v0.28.0

Closes #48

Addresses the breaking API change in
open-telemetry/opentelemetry-collector#3163,
besides the usual version number changes.

Signed-off-by: Fangyi Zhou <me@fangyi.io>

* Use `go mod tidy` instead of `go mod download`

It appears that this magically resolves the go.mod file issue.
