CMS page coverage

[paliarush]

As a Magento Developer, I want to query for CMS page content using the GraphQL API so that I can build basic ecommerce storefronts using only GraphQL

Use cases:

• Developer can query GraphQL for CMS page content and get back all necessary data to render the page on storefront or in 3rd party applications.

Acceptance Criteria

• Only enabled pages will be returned by the API
• Store view context is passed in the HTTP header and only pages relevant to given context will be returned
• Staging versions of the page cannot be queried - only the currently active pages are returned
• [DRAFT] API returns the following info
  • url or url key
  • layout
  • layout update XML?
  • theme?
  • page title
  • content heading
  • rendered (with no Magento-specific directives) or un-rendered page content, depending on configuration
  • meta title, keywords, description
  • parent page(s)

Changes should be covered with web API functional tests. See \Magento\GraphQl\Catalog\ProductViewTest::testQueryAllFieldsSimpleProduct as an example.

Hi @paliarush ,

I have implemented all stuff from requirements possible on Magento 2 Open Source. Some of them I had to avoid due to Commerce only features:

• parent page(s)
• rendered (with no Magento-specific directives) or un-rendered page content, depending on configuration (PageBuilder related stuff)

This is followed up in the following ticket: #106

Also, information under discussion is not added:

• layout update XML
• theme

PR: #105

Thanks!
