[BUG] securityScheme does not support x-amazon-* extensions

[sakiv]

Describe the bug
When adding x-amazon-* extensions to documentation, it drops those attributes.

To Reproduce
Steps to reproduce the behavior:

{
      ...
      "securitySchemes": {
        "customAuthorizer": {
          "type": "apiKey",
          "name": "Authorization",
          "in": "header",
          "description": "JWT token for authenticated users",
          "x-amazon-apigateway-authtype": "custom",
          "x-amazon-apigateway-authorizer": {
            "type": "request",
            "identitySource": "$request.header.Authorization",
            "authorizerUri": "arn:aws:apigateway:${region}:lambda:path/2015-03-31/functions/${function_arns.authorizer}/invocations",
            "authorizerPayloadFormatVersion": "2.0",
            "enableSimpleResponses": true
          }
        }
      },
      ...
}

Expected behavior
x-amazon-* extension attributes should be copied over to the appropriate securityScehme.

Hey @sakiv took me a little longer, so apologies for that, but I have now merged this in and is part of the 0.0.114 release. Thank you for your contribution.
