Support for configurable ignore_changes lifecycle

### Describe the Feature

Currently ignore_changes in cloudposse/terraform-aws-lambda-function is restricted to `last_modified` which is hard coded and not configurable.

_Use case:_

* I want to ignore_changes for `environment` attribute values + last_modified

So that from my module call, I can pass the attributes to ignore when there is any changes.

### Expected Behavior

From the call:

`module "example_lambda_function" {
source = "cloudposse/lambda-function/aws"
version = "0.6.1"

ignore_changes = [environment]
}
`

### Use Case

* I want to ignore_changes for `environment` attribute values + last_modified

### Describe Ideal Solution

Passing the attributes to be ignored when there is any changes in terraform state
