allow axios instance to be provided to plugin

[bmartel]

Proposed changes:

• fix build and update babel dependencies (I was not able to run yarn build on pulling master of the project as of this date, fixed by addressing some dependency issues)
• cherry pick lodash functions for smaller output addresses Slow HMR due to full lodash imports #16
• allow axios instance to be passed in to plugin addresses how to use with JWT token Bearer Authorization #18 Interceptors #7
• expose axios instance to interceptors to allow for custom response handling with tokens addresses Interceptors #7

I noticed there are no tests for this plugin functionality, it however all works as expected. Changes were kept minimal (lock file was regenerated for the dependency changes, so that is the only significant change really) to allow them to be non breaking and a patch level fix.
