Slow response times when obtaining Domain Wide Delegation token and during inbound Authorization header validation about google-auth-library-nodejs HOT 4 OPEN

I have a PR up to resolve, however it will require us to upgrade to Node 16 (which includes JWK support):

• #1762

However, we may be able to release the following PR sooner, which may be more helpful as the /token endpoint would be hit far more often than /cert (longer cache time):

• googleapis/node-gtoken#466

from google-auth-library-nodejs.

We're planning to migrate to newer token endpoints upstream, which may resolve this issue (assuming their aren't any other networking issues, like proxies):

• googleapis/node-gtoken#466

from google-auth-library-nodejs.

@danielbankhead I see this PR updates the /token endpoint but don’t see any updates to the /cert endpoint?

I see this PR updates the /token endpoint but don’t see any updates to the /cert endpoint?

I've conducted an audit an see that there are a few endpoints in this library that will also need to be updated - I'll take care of this shortly.
