Add global level security schemes to collection level auth

[umeshp7]

Fixes: #86
Following openapi schema reproduces this issue.

openapi: 3.0.0
info:
  title: "Reproduce Authorization issue"
  version: 0.0.1
security:
  - BearerAuth: []
paths:
  /status:
    get:
      summary: "status"
      description: "Returns the service version"
      operationId: "get_status"
      responses:
        '200':
          description: "Service info multi-line string"
          content:
            text/plain:
              schema:
                type: "string"
components:
  securitySchemes:
    BearerAuth:
      type: http
      scheme: bearer
      bearerFormat: token

Current behavior:

• All the requests created from paths in this schema have an Auth object with security scheme present at the global level of the schema.
• No auth is added for the ones having in: header. And appropriate headers are added for them.
• No Auth is added at the collection level.

Expected behavior:

• Global security scheme should be added at the collection auth level.
• All the requests which don’t have any auth defined should have ‘Inherit From Parent’ selected in Postman.

This will be executed regardless of line 260 🤔
Can you also add a regression test for this specific case? There should be a case that tests for collection.auth eing empty if in='header'/'query'

Also, why are we doing this in the first place? Why can't apiKey auths be left in the collection.auth property?

I will make the changes and add the test case.

Adding apiKey to collection.auth property which is not recognized as one of the known formats results in an empty selection in the collection level auth dropdown in Postman app. It doesn't default to 'noauth'.

What happens if type is apikey, but in isn't header/query?

Oops! Made changes. @abhijitkane

@abhijitkane
if type is apikey, but in isn't header/query - we should add the auth to collection. So I have made the required changes. Only in case of api-key and header/query the collection level auth will be 'noauth'. Rest of the cases we will add it directly.
