Google-cloud-ruby: Monitoring Docs example for MetricServiceClient#list_time_series returns an error

[thagomizer]

The example for list_time_series doesn't create a valid TimeInterval so if you copy and paste the code you get an error.

Configuring the initialization values for the variables in all the samples is outside the scope of the GAPIC team but, per offline discussion, assigning to myself to configure a single method as a proof-of-concept of how this will be done.

[geigerj]

I did look into this and made an external doc demonstrating how to initialize these values. I'll leave this open until I've moved the example to the external googleapis/googleapis repo.

@omaray is now working on the general problem of how to do this for all GAPIC samples that need configuration.

@geigerj Have the docs been moved to the googleapis/googleapis repo yet? Can this issue be closed?

[geigerj]

@blowmage No. The GAPIC team is not currently maintaining method sample initialization code. This is essentially the same problem as https://github.com/GoogleCloudPlatform/google-cloud-ruby/issues/1866. Since like issues will affect nearly every GAPIC method, I don't think addressing them individually is sustainable. These changes will ultimately come from upstream and not at the google-cloud-ruby level, and I've created https://github.com/googleapis/toolkit/issues/1809 as an uber-issue.
