Add option to specify base uris

[n1ru4l]

Instead of supplying the schema string with lots of urls strings (that are mostly the same) it should be possible to shorten them. Also in case of a refactor there would be less code to change.

Idea:

new (object literal/string) option for function generateRestSchema: baseUri.

Case 1: baseUriis a string

import { generateRestSchema } from '@n1ru4l/graphql-schema-generator-rest'

generateRestSchema({ baseUri: `https://localhost:8080` })

Every route directive option that does not start with a scheme (e.g. https://, http:// is prefixed with the baseUri

Case 2: baseUri is a object literal:

import { generateRestSchema } from '@n1ru4l/graphql-schema-generator-rest'

generateRestSchema({ baseUri: {
  dogs: `https://localhost:8080`,
  cats: `https://localhost:8081`
} })

Every route directive option that does not start with a scheme (e.g. https://, http://) but has a uri directive option which matches a key of the baseUri option object is prefixed with the corresponding value.
