// Modify the version-specific settings of a Lambda function. When you update a
// function, Lambda provisions an instance of the function and its supporting
// resources. If your function connects to a VPC, this process can take a minute.
// During this time, you can't modify the function, but you can still invoke it.
// The LastUpdateStatus , LastUpdateStatusReason , and LastUpdateStatusReasonCode
// fields in the response from GetFunctionConfiguration indicate when the update
// is complete and the function is processing events with the new configuration.
// For more information, see Lambda function states (https://docs.aws.amazon.com/lambda/latest/dg/functions-states.html)
// . These settings can vary between versions of a function and are locked when you
// publish a version. You can't modify the configuration of a published version,
// only the unpublished version. To configure function concurrency, use
// PutFunctionConcurrency . To grant invoke permissions to an Amazon Web Services
// account or Amazon Web Service, use AddPermission .
