Retry for Hyper Errors [unexpected EOF, SSLShutdown]

### Describe the feature

When forming many client connections we get the following errors:
```
unrecognized error from Hyper. If this error should be retried, please file an issue. err=error trying to connect: the SSL session has been shut down: the SSL session has been shut down (hyper::Error(Connect, Ssl(Error { code: ErrorCode(6), cause: None }, X509VerifyResult { code: 0, error: "ok" })))
```
and
```
unrecognized error from Hyper. If this error should be retried, please file an issue. err=error trying to connect: unexpected EOF: unexpected EOF (hyper::Error(Connect, Ssl(Error { code: ErrorCode(5), cause: None }, X509VerifyResult { code: 0, error: "ok" })))
```

### Use Case

We should still be able to retry if we make too many client connections and our host shut downs our sockets.

### Proposed Solution

We should retry these errors as transient errors [here](https://github.com/awslabs/aws-sdk-rust/blob/c1b7d791516e7c77aa88573742e9252fb49a4211/sdk/aws-smithy-client/src/hyper_ext.rs#L210).
