Ensure HttpEntry bean is request scoped in aai-common

- declare separate request scoped HttpEntry beans
- leave the existing prototype scoped HttpEntry beans in place [1]
- disable flaky test

[1] some of the existing tests (in traversal+resources) use them in a non-web context
In those cases, using request scoped beans requires extra annotations to make it work
