Use case description

It'll be nice to have provider section fully covered by schema validation (for AWS provider case)

Proposed solution

Follow up to #6562, with which only schema placeholder for provider was configured.

Configuration should probably be done directly in: lib/plugins/aws/provider/awsProvider.js, what it covers was split into following issues:

• Config schema: Define AWS "provider" properties (top level only) #8016 Top level only properties
• Config schema: Define AWS "functions[]" section properties #8017 Function related properties
• Config schema: Define AWS "http" function event properties #8018 API Gateway related properties
• Config schema: Define AWS "websocket" function event properties #8019 Websocket related properties
• Config schema: Define AWS "alb" function event properties #8020 ALB related properties
• Config schema: Define AWS "httpApi" function event properties #8021 HTTP API related properties
• Config schema: Define AWS "s3" function event properties #8031 S3 related properties

After all above issues are addressed, we may remove schema relaxation configured in lib/classes/ConfigSchemaHandler/index.js
