🤝 Honor backend CA certificates

[acw]

This should work for both static certificates in the TOML file, presuming you can get them in in a reasonable format, and through dynamic backends.

I've added some test cases, which required adding a serial_test dependency so that the existing client cert test doesn't stomp over the execution requirement. I figured it was nice to leave this functionality in, as there may be more complicated situations in which just using a dynamic backends flag was inconvenient.

@acw is there anything stopping us from merging this work?

Is there an example of what this reasonable format should look like? Also, would it be possible to supply a filepath instead of in-lining into the TOML file?

@acw would it be possible to have some tests added to /lib/src/config/unit_tests.rs which test out the new fastly.toml fields? 🤞

Is there an example of what this reasonable format should look like?

Only in the test cases. I could put an example config somewhere, but I'm not sure where? Do we have a standard place to put examples?

@JakeChampion Now with tests, which can be showed as examples, and support for file references. Also did arrays, while I was in there, so you can add multiple certs.
