* Add in missing try keyword.

* Add a way to fix a date for AWSSigV4Signer::signRequest, and add tests for AWSSigV4Signer::signRequest.

* Add SigV4 x Presigned Request integration tests using STS::getCallerIdentity and S3::putObject.

* Rename integration test directory and file for STS to be more specific.

* Update S3ErrorWith200 middleware to fix S3XCTestCase::tearDown(). Delete tearDown() from presigned request integration test now that it is redundant.

* chore: Update models (#1301)

* fix: Preserve data after reading response body stream in S3/200 middleware (#1303)

* chore: Updates version to 0.34.0

* Improve comments and variable names on the EventBridge integration test.

* Update documentation comment to mention correct description of the test class.

* Remove unncessary string literal in code.

* Increase pause timer to prevent spurious failures.

* Add SigV4A integration test that uses S3's multi-region access point.

* feat: Add integration tests to CI (#1308)

* Finish SigV4A integration tests that use S3 MRAP.

* Add SigV4A signing flow integration test that uses CloudFrontKeyValueStore.

* Add auth scheme resolving step for convenience inits of client config in case they aren't provided.

* Fix ktlint.

* feat!: Provide HTTP request components by closure instead of protocol (#1317)

* Address PR comments from Josh.

* Fix SigV4A EventBridge integration test.

* Add time buffer between MRAP deletion completion and deleting buckets. Integ test fails in CI saying bucket has MRAP associated, but MRAP is deleted when checked in console. Perhaps attempting to delete bucket as soon as MRAP deletion completes is causing this error.

* Fix data type.

* Fix method used to check MRAP deletion completion from checking against a literal integer 1, to checking against list ofMRAP names existing on account.

* Copy generated SDK code from feat/sra-identity-and-auth so it doesn't show up in github diff.
