load babel options in graphql-tag-pluck

[rwe]

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

graphql-codegen was silently ignoring source files and not extracting documents.
I was able to track it down to our use of the parser plugin explicitResourceManagement, which is declared in the babelrc.

But it turns out that graphql-tag-pluck hardcodes babel options based on file extensions ¹, and passes those directly to parse() ² without possibility of intervention. It ignores existing babel configuration.

Describe the solution you'd like

graphql-tag-plug should attempt to use babel.loadPartialConfig ³, and use that if it succeeds.

Describe alternatives you've considered

Alternatively, allow passing a list of plugins or babel options overrides through. Note that this might require plumbing up a few levels if interfaces through CodeFileLoader and graphql-codegen itself to make sure it's properly exposed.
