Amazon.Lambda.Tools (7.0.0)

• When deploying a durable function with deploy-function or update-function-config, automatically attach the AWSLambdaBasicDurableExecutionRolePolicy managed policy to a tool-created execution role, and warn when a user-supplied role is missing it.
• Added --invoke-mode switch to the invoke-function command with values RequestResponse (default), Event, Stream and DurableExecution. Stream invokes the function with InvokeWithResponseStream and streams the response to the console; Event invokes asynchronously and displays any function error and the durable execution ARN; DurableExecution invokes asynchronously and monitors the durable execution by polling GetDurableExecution and GetDurableExecutionHistory, resolving the latest published version ARN when a function name is supplied
• The deploy-function and update-function-config commands now write the new function version ARN to the output when --function-publish is set to true
• [Breaking Change] Tool's minimum .NET version updated from .NET 6 to .NET 8
• Added --file-system-configs, --durable-execution-timeout and --durable-retention-period switches to the deploy-function and update-function-config commands to configure the function's file system (Amazon EFS/S3) and durable execution settings
