> Currently the Json Config Store retains a reference to the ConfiguredObjectRecords passed
in in update and create operations.  If the ConfiguredObjectRecord is actually one generated
from AbstractConfiguredObject.asObjectRecord() then the records value may change, and querying
the attributes of the record will obtain locks on the underlying configured object.
> To prevent deadlocks and to ensure that the correct values get written to the store,
a deep copy of the record should be taken before storing.
