jfwood 78dfbc6463 Add order plugin metadata entity and logic
To support certificate plugin workflows, plugins needs a means to persist
their state in between method invocations by Barbican core. This CR adds
that persistence feature, by adding a new SQLAlchemy model and migration file,
and a new repository.
