Ability to set "schemes" programatically

[dskoda1]

Is your feature request related to a problem? Please describe.

A service i'm working on requires scheme to be http for local development, and preferably only https once its deployed. If the schemes could be controlled programatically, this would be possible!

Currently I can only set schemes to https http to make this work; and its a lose lose, because locally, I need to switch it to http to get requests working, and when deployed, http is still an option even though I don't want it to be one.

Describe the solution you'd like

Add an option to the SwaggerInfo struct created in #220 to set the scheme.

Describe alternatives you've considered

Open to other options people might think of.

I'm happy to take a stab at this by the way!

So it looks like all the other configurations which can be set programmatically are being set in a template, within a template - gen.go. The intermediate template variables are being set in the parser. These are being set on the SwaggerProps struct of upstream go-openapi/spec repository.

Unfortunately I can't figure out a way to set up a template representation of the array of schemes in the second link (parser) such that it can be stored in the SwaggerProps.Schemes property, since its a slice of strings, not just a string like the other variables.

Definitely a bit of a roadblock, any ideas on how this could be worked around? Possibly an option is to make use of the VendorExtensible aspect of the spec.Swagger type, however i'm not very familiar with how that works.

I've just created a PR for this. Good luck!
