No really, add the standard retry strategy to the orchestrator (#2741)

## Description
<!--- Describe your changes in detail -->
This PR adds support for the Standard retry strategy. The standard
strategy will be inserted into a service's config bag if a retry config
was set. Otherwise, unless another retry strategy was already set, a
`NeverRetryStrategy` will be set. This seemed like a reasonable default,
but I'm open to suggestions.

## Testing
<!--- Please describe in detail how you tested your changes -->
<!--- Include details of your testing environment, and the tests you ran
to -->
<!--- see how your change affects other areas of the code, etc. -->
tests are included
