Feature request: support for x-discriminator

[RomanHotsiy]

swagger2openapi converts x-required, x-nullable and a few others vendor extensions to corresponding OpenAPI 3 features.

Would be great to also support x-discriminator:

x-discriminator:
  propertyName: type
  mapping:
    visa: "#/definitions/paymentMethodVisa"
    mastercard: "#/definitions/paymentMethodMastercard"
    amex: "#/definitions/paymentMethodAmex"

One of the things to not forget is to map JSON pointers from mapping field to new locations.

Hello @MikeRalphson, thanks for this great library!

I'm eagerly awaiting the next release. When have you planned on doing this?

(Sorry to be a pest!)

[MikeRalphson]

HI @leonardehrenfried - thanks, and you're not being a pest! I'm kind of waiting on lerna 3 to come out of beta, to try and ensure there are no problems publishing from a new mono-repo layout. If it drags on too long, I'll bite the bullet and attempt to publish the new version.

Included in swagger2openapi v3.0.x.
