* chore: Updates version to 0.35.0

* Add customizations to auth resolve process.

Add internal modeled layer for services (S3, EventBridge) that use rules-based auth scheme resolver.

Rules-based auth scheme resolver work wrap-up.

Wrap-up presign / presign-url refactor.

Wrap-up refactor for fitting in rules-based auth scheme resolver.

Update test cases to include new middlewares.

Move requestSignature getter / setter/ key from aws middleware context extension to here. Also, add saving requestSignature to SignerMiddleware for consumption by event stream signing.

* Add signEvent API to Signer protocol, and rename sign to signRequest.

* Add mock auth scheme resolver, mock auth schemes, mock identity, mock identity resolver, and mock signer to use for middleware unit tests.

* Add unit tests for AuthSchemeMiddleware and SignerMiddleware.

* Update MockSigner to conform to modified Signer API with signEvent.

* Rename directory containing mocks for auth tests from AuthTest to AuthTestUtil.
