### 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`.

### Describe alternatives you've considered

      onCanceled = cancel => {
        if (!request) {
          return;
        }
        reject(!cancel || cancel.type ? new CanceledError(null, config, request) : cancel);
        request.abort();
        request = null;
      };

      if (config.signal) {
        config.signal.aborted ? onCanceled() : config.signal.addEventListener('abort', onCanceled);

    const protocol = parseProtocol(fullPath);
    if (protocol && platform.protocols.indexOf(protocol) === -1) {
      reject(new AxiosError('Unsupported protocol ' + protocol + ':', AxiosError.ERR_BAD_REQUEST, config));
      return;
    }
    
    request.send(requestData || null);
  });
