Allow Build Hang Config to be set in YAML bamboo specs

It is currently not possible to override the build hang configuration with YAML specs.

Suggesting something similar to the clean-working-dir property under other (which I believe is the only thing you can set at the moment under "other" for YAML specs).

Perhaps a sample yaml could look like

---
plan:

...

Job 1:

  ...

  other:

  build-hang-config:

    log-quiet-time: 20

    build-time-multiplier: 2

    build-queue-timeout: 30
