Include the adapters in the library

[aminnairi]

Is your feature request related to a problem? Please describe.
If starting off from scratch without using the template, users will have to spend some time defining an adapter. This can be quite tedious for newcomers or users that only want to focus on the business and not on the implementation details. Adapters should be included in the library, allowing users to use a set of default adapters in order to send the requests.

Describe the solution you'd like
Include the createHttpAdapter & createExpressAdapter inside the library instead of having to always define it manually for users that don't want to start off with the template.

Describe alternatives you've considered
None.

Additional context
None.
