Improve GraphQL caching

[paliarush]

As a Magento developer, I want appropriate GraphQL queries to be cached so that I get the maximum performance out of my applications and integrations that leverage GraphQL framework.

• GraphQL config caching: invalidate cache on certain dynamic events (as opposed to code modifications), like
  • adding/removing/updating EAV attribute
• Server-side query caching
