/** holds data provider key, description, and associated shared library file information
The metadata class is used in a lazy load implementation in
QgsProviderRegistry. To save memory, data providers are only actually
loaded via QLibrary calls if they're to be used. (Though they're all
iteratively loaded once to get their metadata information, and then
unloaded when the QgsProviderRegistry is created.) QgsProviderMetadata
supplies enough information to be able to later load the associated shared
library object.
