Port redacting sensitive body to orchestrator (#2972)

## Motivation and Context
Fixes https://github.com/awslabs/smithy-rs/issues/2926

## Description
This PR ports logic implemented in
https://github.com/awslabs/smithy-rs/pull/2603. Thankfully, even though
we did not port this at the time of the orchestrator launch, the
orchestrator has not logged sensitive bodies because we have never
logged response bodies in the orchestrator code.

The code changes in this PR
- now logs response bodies in `try_attempt`
- ports the logic from the previous PR in question to the orchestrator,
via an interceptor

Now, when credentials providers in `aws_config` need to say "I want to
redact a response body"
([example](https://github.com/awslabs/smithy-rs/blob/2c27834f90b0585dba60606f9da6246b341227d6/aws/rust-runtime/aws-config/src/http_credential_provider.rs#L48)

)
when middleware is gone, they can pass an interceptor
`SensitiveOutputInterceptor` to `Config` of whatever clients they are
using.

## Testing
Depends on the existing tests.

Without the logic ported over the orchestrator and by logging response
bodies unconditionally in `try_attempt`, we got the following failures.
After we've ported the logic, they now pass.
```
    default_provider::credentials::test::ecs_assume_role
    default_provider::credentials::test::imds_assume_role
    default_provider::credentials::test::sso_assume_role
    default_provider::credentials::test::web_identity_token_env
    default_provider::credentials::test::web_identity_token_profile
    default_provider::credentials::test::web_identity_token_source_profile
    profile::credentials::test::e2e_assume_role
    profile::credentials::test::region_override
    profile::credentials::test::retry_on_error
```
