chore: bump grpc gem to 1.43.1

[perek]

Due to a bug in grpc gem you cannot compile this plugin after 10.0 on ARM architecture grpc/grpc#23889

We need to bump this dep up to support native arm extensions

[perek]

needed to bump this as well

Per evaluation in http://b/219963999, these versions look good. LGTM

Looks like this also requires upgrading to >= Ruby 2.5.0. So there are more validations we need to do internally.

[qingling128]

In fact, I just checked the package. We are already using Ruby 2.6.9 there: https://github.com/GoogleCloudPlatform/google-fluentd/blob/250f1343be7c90f35101c4dae708090d257e6ae6/config/software/ruby.rb#L31. So it should be fine to just remove 2.4 from the testing grid.

Sent two PRs:

• Remove Ruby 2.4 and add 2.7 in the testing grid. #485
• Update README to use Ruby 2.6 instead. google-fluentd#374

@perek - Some updates: We have a custom build of google-fluentd with this new gem version now. However, the new gRPC version breaks support on a version of Amazon AMI we support (based on CentOS 6), so we might not be able to release a formal version before we can claim end of support for that.

Are you interested in trying out a custom build instead?

[perek]

@qingling128 yes I am lmk how to consume it

[perek]

i am building fluentd from scratch, so I think just a new release would work for me too so I can swap the ruby gems

See also GoogleCloudPlatform/google-fluentd#376

@perek - We might not be able to do a release soon due to the breakage of CentOS 6. If you are building from scratch, would a custom gem push work for you? something like 0.12.5.rc.1?

[igorpeshansky]

I'm going to try to get our Amazon AMI story under control, so we can actually release.

[perek]

That will work perfect for me @qingling128

[qingling128]

Here we go: https://rubygems.org/gems/fluent-plugin-google-cloud/versions/0.12.5.rc.1

FYI, we're seeing about 15-20 MB increased memory usage overall after upgrading:

Purportedly there are some memory fixes in 1.45.0, so I will open a PR to upgrade to it. Not sure if it will make a difference here but it would be good to pick it up anyway on its own merits.
