We're rolling out new rules around the node assert library, the first of which is enforcing the use of assert/strict. This means we don't need to use the strict version of methods, as the standard version will work that way by default.
This caught some gotchas in our existing usage of assert where the lack of strict mode had unexpected results:
- Url matching needs to be done on `url.href` see aa58b354a4
- Null and undefined are not the same thing, there were a few cases of this being confused
- Particularly questionable changes in [PostExporter tests](c1a468744b) tracked [here](https://github.com/TryGhost/Team/issues/3505).
- A typo see eaac9c293a
Moving forward, using assert strict should help us to catch unexpected behaviour, particularly around nulls and undefineds during implementation.

- we've deemed it useful to start to return `Content-Version` for all
API requests, because it becomes useful to know which version of Ghost
a response has come from in logs
- this should also help us detect Admin<->Ghost API mismatches, which
was the cause of a bug recently (ref'd issue)

- Having a 'Origin' in vary header value present on each `OPTIONS` allows to correctly bucket "allowed CORS" and "disallowed CORS" responses in shared caches

- The codebase has ambiguous behavior with OPTIONS request. Adding tests covering edge cases for all possible variations of OPTIONS responses is the first step to solving cahceability of these requests.
- The obvious question if you look into the changeset itself would also be: "WTF did you do with test suite naming? What are these changes in admin and click tracking suites? You having a bad day Naz?". The answer is "yes" (╯°□°)╯︵ ┻━┻
- On a serious note. I've introduced multiple hacks here that should be fixed:
1. Forced test suite execution order for options request - extreme blasphemy. This was last resort decision. I went deep into trying to fixup the server shutdown in the "admin" test suite, which cascaded into failing "click tracking" suite, which has shortcomings on it's own (see notes left in that suite)
2. Exposed "ghostServer" from the e2e-framework's "getAgentsWithFrontend" method. Exposing ghostServer to be able to shut it down (or do other manipulations) was one of the pitfalls we had in the previous test utils, which ended up plaguing the test codebase. Ideally the framework should only be exposing the agents and the rest would happen behind the scenes.
- To fix the hacks above I've raised a cleanup issue (https://github.com/TryGhost/Toolbox/issues/471). I'm very sorry for this mess. The issue at hand has very little to do with fixing the e2e framework, so leaving things "as is".
