CORE-191: list/get/create import jobs works for requester-pays workspace

[davidangb]

Creating, getting, and listing async data table import jobs did not work in requester-pays workspaces.

As part of these operations, Orchestration queries Rawls. It sends a workspace namespace+name, gets a response, and extracts the workspaceId from the response. However, the request it sent was for the entire workspace object, including bucket info. This would cause the request to fail for RP workspaces.

This PR introduces a new, optimized getWorkspaceId method for Orch to query Rawls. This request does not ask anything about buckets and therefore hits no problems in RP workspaces.

Have you read CONTRIBUTING.md lately? If not, do that first.

I, the developer opening this PR, do solemnly pinky swear that:

• I've followed the instructions if I've made any changes to the API, especially if they're breaking changes
• I've updated the FISMA documentation if I've made any security-related changes, including auth, encryption, or auditing

In all cases:

• Get two thumbsworth of review and PO signoff if necessary
• Verify all tests go green
• Squash and merge. Make sure your branch deletes; GitHub should do this for you.
• Test this change deployed correctly and works on dev environment after deployment

I needed to update this example test data; UUID.fromString("id") would cause problems. This is more realistic test data anyway.
