Support PMF singleton pattern

 Description  « Hide
Would be nice to allow support for a singleton PMF pattern by allowing a PMF property to define that the PMF with a particular name (JDO name, or persistence-unit name) is registered and any subsequent attempt to generate the PMF of that name logs a warning and returns the existing PMF.

Setting the PMF property "datanucleus.singletonPMFForName" to true results in a single PMF for that PMF/persistence-unit name being created (and returned when subsequently requested). When it is closed then a new one can be created
