Config schema: Define AWS "functions[]" section properties

[medikoo]

Use case description

It'll be nice to have functions[] section fully validated for AWS provider case.

Proposed solution

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

• environment
• memorySize
• role
• runtime
• timeout
• tracing.lambda
• versionFunctions
• vpc

2. Define schema for all properties (apart of events) at functions[] level

Note: Each event is covered with dedicated issue, and is not in scope here.

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

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

Lines 143 to 145 in d403d9c

	function: {
	// TODO: Complete schema, see https://github.com/serverless/serverless/issues/8017
	properties: { handler: { type: 'string' } },

Reopenning, as apparently we still miss definitions for destinations, maximumEventAge and maximumRetryAttempts at functions[] level.

Also after adding those, we need to ensure that relaxation as configured here:

serverless/lib/classes/ConfigSchemaHandler/index.js

Lines 214 to 216 in 38c2047

	this.schema.properties.functions.patternProperties[
	FUNCTION_NAME_PATTERN
	].additionalProperties = true;

)
no longer applies to functions[] properties, when we're in context of AWS provider
