Use GraphQL data in full code quality report

When graphql_code_quality_full_report feature flag is enabled
load pipeline code quality report data via GraphQL
update specs to test for feature flag set to true/false
update issue parser to handle all-caps issue severities
Add a skeleton loader to the pipeline code quality report
