Linting / IDE integration

[timble-one]

• Why doesn't graphql-linting integrate into webstorm at all
  • invalid fields aren't hightlightet at all (flexirent-backend -> mb pro)
  • does webstorm recognize the graphql-schema? do we have a graphql.config.yml?
• Importing stuff in Webstorm is tedious because functions and types must be importat separately but aren't automatically
• Why do invalid fields not show an eslint-error on flexirent-admin/IndividualProductPage_individualProduct fragment?
  • can't eslint detect invalid graphql-fields?
• Is there a trick to tell eslint which fields are used by the inputProps Helper?
  • Then it would not bee necessary to disable relay/unused-fields on the DetailPages
  • Perhaps one would have to implement a eslint-plugin? Or perhaps there is an even simpler trick :)

Tried to fix the problem with the eslint-rule relay/unused-fields
See feature/enable-eslint-relay-unused-fields branches. Including flexirent-admin repository.
