Allow dynamodb health check when credentials are not provided in options
Make the options and the credentials of dynamo db check optional. The AWS credentials and region in my project were set in the env params, it will be better to allow the user to leave the options empty. Unit test added and fully tested.
I'm reading this PR and I think it might solve the same problem https://github.com/Xabaril/AspNetCore.Diagnostics.HealthChecks/pull/653
