Create Js-Data V3 Compatible Adapter

[BlairAllegroTech]

Js-data-http V3, has 3 variants, with Axios, without Axios uses Fetch and the Node version.
In order to support these i suggest externalising the creation of the HTTP adapter variant to be used.

The variant to be used could be passed as a parameter:

1. Dependency injection.
2. or a value to indicate which variant to use.

Haven't decided which will approach to use yet but normally i think 1. would be best
