merge of library swagger generated classes into SDK

[evias]

Issue scope

The nem2-library-js swagger generated classes must be merged over in the SDK. This merge process will include following folders of the library :

• src/ApiClient.js
• src/api/
• src/listeners/
• src/model/

The merge should happen with folder structure such that in the SDK, the folder structure will be :

• src/infrastructure/api
• src/infrastructure/model
• src/infrastructure/listeners

After the merge of those classes, the SDK's src/infrastructure/*Http.ts services classes must be updated to use the new DTOs and routes.
