In some situations it may be useful to have a separate DiagnosticManager
instance, and then later of move the contents of that instance back to the
"main" DiagnosticManager. For example, when silently retrying some operation
with different parameters, depending on whether the retry succeeded or failed,
LLDB may want to present a different set of diagnostics to the user (the ones
generated on the first try vs the retry). Implement DiagnosticManager::Consume
to allow for this use case.
