[CORE-227] Deprecate queueStatus API

[marctalbott]

Ticket: CORE-227

• Deprecates this API as it is not used and no longer returns valuable information as Rawls submits workflows to Cromwell much faster than it did when the API was introduced. The API will be removed as part of CORE-255

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
