[yoshi-automation]

BREAKING CHANGE: In addition to the v4beta client features, this change also removes support for any string template paths relating to projectPath and companyPath, it now supports tenantPath and companyOldPath instead.

The doc failure here is because it's looking for a link that has yet to be committed to master. I'm pretty ignorant to Kokoro but it seems like we shouldn't be testing against master, but the branch being PR'd instead?

Aside from that, this is one hefty PR - it includes new features, breaking changes and what looks like some analytics code? I've updated the PR overview to include a mention of the breaking changes, so whoever merges should make sure it (or something similar) is included in the extended message.

The link I see failing - [404] https://github.com/googleapis/googleapis/blob/master/google/cloud/talent/v4beta1/resume_service.proto

is at the googleapis/googleapis repo. Since this generation is based off of it, we need to understand why it's missing there.

[jkwlui]

I see the problem now. Some files actually got removed since this generation:

	deleted:    protos/google/cloud/talent/v4beta1/resume_service.proto
	deleted:    src/v4beta1/doc/google/cloud/talent/v4beta1/doc_resume_service.js
	deleted:    src/v4beta1/resume_service_client.js
	deleted:    src/v4beta1/resume_service_client_config.json

But neither synthtool/gapic remove files that are not suppose to be there, we didn't catch that.

I had to rm -rf protos src/v4beta1 and run synthtool locally to see that they were removed.
