Fixes: #1340

Description of the change:

This change makes some jwt report get handlers non-async. Having them as async was causing a timeout due to the vertx event loop being blocked while waiting for a report response from the reports sidecar.

Motivation for the change:

See #1340
It makes sense that we wouldn't want these handlers async since we are actively waiting on a http response ourselves and are planning to return it.

How to manually test:

1. Run cryostat normally with smoketest
2. Create a recording and archive it after a few seconds.
3. Press view report on the kebab (this uses the jwt handler) (Do not view a report within the iframe as this caches the report).
4. Notice that the report is generated without a timeout as opposed to before.

Makes sense. itests seem to be flaky failing for unrelated reasons. Will test and verify as soon as images are available.
