Updated google pubsub grpc deps to latest version

[DanieleSassoli]

Purpose

Updates the versions of the following dependencies so to avoid conflicts with more recent versions of pubsub api.

"com.google.api.grpc;grpc-google-cloud-pubsub-v1;1.61.0;protobuf", 
"io.grpc;grpc-auth;1.21.0",
"com.google.auth;google-auth-library-oauth2-http;0.16.1"

Background Context

While developing a component that integrates with pubsub we tried using the latest version of it's apis but this caused a conflict with alpakka's version of the pubsub apis which where very obsolete.
For good measure we also updated the other related components which only had minor version changes.

The change looks good, but since the data classes have changes, this will have to wait until Alpakka 1.1.0.

When is Alpakka 1.1.0 planned to be released?
Is there any snapshot build available in any public repository in the meantime?

[DanieleSassoli]

Following #1788 (comment) I think this build should pass if we re-run it. Is there a nice way of re-triggering a build or do I have to push a new commit?

[ennru]

I retriggered it now.

[DanieleSassoli]

Thanks @ennru, I noticed you moved the milestone to 2.0.0, does this mean it won't get released until alpakka 2.0.0 gets released? I don't see any breaking changes. Also this PR will already be obsolete in a couple months time.

[ennru]

We just decided to rename the upcoming releases. 1.1.0 next week as we add two new connectors.
PRs changing existing APIs or changing dependencies considerably require a major release. We expect to release 2.0.0 in September and will have milestone builds by mid-August.

[DanieleSassoli]

Cool, thanks for the clarification, I'll keep an eye on the PR and try to keep it as up to date as I manage.

[ennru]

Thank you for your patience.

[ennru]

LGTM.

[ennru]

Thank you! Great that you engaged to fix it.

[lucamilanesio]

Hi @ennru this is great! Any ETA for the next release that will include this fix?

[ennru]

We hope to get it together by end of September 2019.
Once master builds successfully, you may try snapshots https://doc.akka.io/docs/alpakka/snapshot/google-cloud-pub-sub-grpc.html

Hi @ennru, we are keen to start adopting Alpakka 2.0.0 with the updated PubSub libraries.
How are things going for the release? You were mentioning September 2019, which was last month.

Thanks in advance for your feedback.

P.S. I believe the stable 1.1.x. branch, sooner or later, would need this fix. The PubSub libraries included there are going EOL very soon and the GCloud service won't serve them anymore.

[ennru]

Yes, we couldn't match the pace we aimed for. The plan is to start with Alpakka 2.0 milestone builds during the next weeks.
