Add advice on user agents?

Specific to packages wrapping APIs.

Adding an user agent.
Should that user agent be different for package developers themselves and for CI.

Linked to #478 (value added by a wrapper)

This is all very much "in flux". I think use of http2 in particular should translate to a general principle of using the same credentials/agents for CI, but also ensuring everything is redacted via httptest2. For other http systems recommendations would differ. So there seems to currently be a strong dependence of recommendations on http systems, but if we presume a general transition towards http2, then we can also presume a direction of future evolution of our recommendations in this regard.

Thanks! But user agents aren't really confidential info?

• the package should provide a default user agent
• the package should let users override it (?)
• the package might change the user agent based on context (CI, package developers)

Why would that be different when using, say, curl?
