Config schema: Define AWS "http" function event properties

[medikoo]

Use case description

It'll be nice to have http event fully covered by schema validation

Proposed solution

1. Define schema for following properties at provider level (that's part of Config schema: Define AWS "provider" properties #8022)

• apiGateway (apiKeySourceType, binaryMediaTypes, description, metrics, minimumCompressionSize, restApiId, restApiRootResourceId, restApiRootResources, websocketApiId)
• apiKeys
• apiName
• endpointType
• logs.restApi (Addressed with feat(AJV): Add Rest api logs definition #8309)
• resourcePolicy (Addressed with fix(Config Schema): validate resourcePolicy is array #8051)
• tracing.apiGateway (Addressed with Add base definition of properties #8222)
• usagePlan

Should be done directly in: lib/plugins/aws/provider/awsProvider.js:

serverless/lib/plugins/aws/provider/awsProvider.js

Lines 141 to 142 in d403d9c

	// TODO: Complete schema, see https://github.com/serverless/serverless/issues/8016
	serverless.configSchemaHandler.defineProvider('aws', {

2. Define schema of all http event properties

Done in #8301
