### Is your feature request related to a problem? Please describe.

I am creating a library that will mostly be used in electron projects. The library needs to perform http request to a localhost server that uses a self signed certificate, so I need to use https.Agent. The problem is, that axios uses the xhr adapter instead of the http adapter. When i try to import the correct adapter from `axios/lib/adapters/http` I get the error `ERR_PACKAGE_PATH_NOT_EXPORTED`. 

### Describe the solution you'd like

I need a way to tell axios to always use the http adapter. The easiest way to do this is by exposing `axios/lib/adapters/http`.

          return;
