make it possible to passthrough functions to the swagger-initializer.js

[Uzlopak]

Closes #25

I know that the coverage is failing, but writing 100% test coverage would be a waste of time if the approach would not be accepted.

So currently we JSON.stringify uiConfig and initOAuth which is basically removing functions as functions are not per definition serializable. But with my super simple serializiation function, I can serialize an Object as best as possible. Yeah sure... ES6 Maps and Sets and what not are not supported or yet. But whatever. Supplying the initOAuth and uiConfig per swagger-initialization.js so we can support functions.

Removes the initOAuth and the uiConfig routes as they dont need to be fetched again.

Docs would need to be updated to mention no support for Maps, Sets etc. until they're added, right?

[Uzlopak]

Ok, seems like you have interest in this solution. Added Maps and Sets. but tbh... they werend supported till now neither.

I think the solution is complete.

Let wait a bit for the others to review before merging.

LGTM, as Climba said, need some more eyes on it.

Is the CI linting failure an issue?

Is the CI linting failure an issue?

Seems like a bug of standard.
It should not crash itself as a linting tools.

[Uzlopak]

I investigated why suddenly linting is failing, and I have no clue. Locally it works. If I remove the standard rules in package.json i get the same error as in the ci.

The linting issue can be found here estools/esquery#135
Not related to our code

[Uzlopak]

Ok. Linting is working now after equery was fixed

@mcollina
Should the serializer be a separate npm package?

lgtm

[mcollina]

No I don't think it's needed at this time.
