go.mod: update replace dependencies

[powersj]

Feature Request

Opening a feature request kicks off a discussion.

Proposal:

There are currently four replace stanzas in our go.mod. Looking at the bugs that were opened for each of these, at least the last 3 appear to be closed and resolved.

If updating or removing the replace stanzas is not possible, then add a reason as to why. Investigate the following:

• github.com/satori/go.uuid => github.com/gofrs/uuid via NewV4: non-random uuid satori/go.uuid#73
• github.com/mdlayher/apcupsd => github.com/influxdata/apcupsd via ALARMDEL can't be parsed as a time.Duration mdlayher/apcupsd#10
• github.com/cisco-ie/nx-telemetry-proto => github.com/sbezverk/nx-telemetry-proto via update dependency and add generation make file cisco-ie/nx-telemetry-proto#1
• github.com/riemann/riemann-go-client => github.com/dstrand1/riemann-go-client via Upgrade to new protobuf library riemann/riemann-go-client#27

The third one appears to be a PR against a fork. The fork itself has the protobuf files now. The second and fourth appear to be resolved and in master. The first may require additional investigation.

next steps: review the checklist

If the nx-telemetry-proto replacement is still needed, let's add a comment with a date in the go.mod so we know in the future when to check again.
