Some burnin steps are idempotent: e.g. reinstalling an instance (fromburning p.o.v.) can be done multiple times without any side-effects thatwould affect later burnin steps. As such, failing the whole burninprocess due a reinstall failure is undesirable....

This patch adds the framework for, and enables lockless OpQueryInstances. Thismeans that instances will be shown in ERROR_up or ERROR_down state, even thoughthis is not an error (but just an in-progress job).
The framework is implemented as follows:...
