[Feature/multi_tenancy] Implement client.bulk in SDK Client

[dbwiddis]

Description

Adds an SDKClient equivalent to client.bulk().

Summary of changes (helpful for reviewers):

1. Added a new DataObjectRequest parent class. I originally started with a tagging interface just to help method signatures, but realized that four classes duplicated the same code for the index, id, and tenantId fields, so refactored those (and the associated builder code) into the superclass. Existing unit tests cover this change. caeea21
2. Added a new DataObjectResponse parent class similar to above, refactoring the id and parser fields from the subclass. Existing unit tests cover this change. 445936b (part 1)
3. Added new BulkDataObjectRequest and BulkDataObjectResponse classes and unit tests. Added a failed field to the response superclass to track failures/errors. 445936b (part 2)
4. Added the interface and stubbed implementations for the SdkClient .bulk() method, and unit tests 22dccf4
5. Implemented the new interface method in all 3 clients. The local and remote implementations use the OpenSearch bulk request natively. The DynamoDB implementation simply iterates the bulk request and calls existing code for the individual requests; this is not the most efficient but necessary to preserve ordering. If all the bulk requests are put and delete, it's possible to optimize this with DDB BulkWrite, which is a good future optimization; however since our primary use case uses update I'm deferring that complexity. ee30d21
6. Additional refactoring in response to code review: move the details of ingest_took to a lower level 7f19078
7. More parameters in the sdkclient request/response to handle the needed implementation 05a64d1
8. Implementation and tests e2a5ec6

In addition there are several whitespace / import reordering changes due to spotless not having been run on the common module.

Will be handled integ tests in #2818
