/kind hotfix

/kind cleanup

What this PR does / Why we need it:

• Routine update of dependencies, especially fixed dependencies
• There is no longer a warning about installing google-auth-library. This is not imported by the SDK code and is included grpc-js so has been removed as a direct dependency
• This includes the security update in Bump the y18n nodejs dependency to 4.0.1 to fix CVE-2020-7774 #2038. Hopefully merging goes ok

Which issue(s) this PR fixes:
