[KushalP]

Upgrading from v1.0.1.

Upgrading related dependencies

The following dependencies also had to be upgraded:

• go.opentelemetry.io/contrib/instrumentation/google.golang.org/grpc/otelgrpc v0.26.1
  From v0.25.0. This gets rid of a transitive dependency on go.opentelemetry.io/otel@v1.0.1.
• google.golang.org/genproto@v0.0.0-20211118181313-81c1377c94b1

Looks like there's already code in place to deal with the relative path case: https://github.com/etcd-io/etcd/blob/main/client/v3/internal/endpoint/endpoint.go#L103

try running scripts/fix.sh to cleanup the deps failing in static [1]

@hexfusion thanks for the tip about scripts/fix.sh ! I had to amend the last commit here. I've made sure all commits here work cleanly with that script. I'll also update the PR title and description as it's slightly larger than what was originally intended here.

[hexfusion]

once tests are green let's squash these commits please, thanks!

[KushalP]

Is it normal for some of these builds to take 30+ minutes to complete?

[hexfusion]

looks like the tests are in a pending state might be some sort of throttling, but it is not expected.

[KushalP]

Have squashed this change into a single commit as requested. I've also moved grpc-go back to v1.41.0 so there's less of a concern about this change.

[KushalP]

Amended the commit message and PR description as they both referenced a newer version that isn't part of the diff here.
