With this a data provider factory instance can advertise special capabilities that can be applied for the given data provider.

This commit adds code for that and implements the "canCreate" and "canDelete" capability. "canCreate" indicates that this instance can create a derived data provider. Use the IDataProviderFactory method getAdapter(ITmfDataProviderConfigurator) to obtains a ITmfDataProviderConfigurator. This interface has methods to get List describing the parameters needed to create a derived data provider using method createDataProvider.

"canDelete" indicates a the data provider can be deleted using the method ITmfDataProviderConfigurator#deleteDataProviderDescriptor.

[Added] capabilities data structure to IDataProviderDescriptor

Just to make sure, "canDelete" indicates that THIS data provider can be deleted, it is not related to deleting derived data providers that this data provider has created, correct? So it's the derived data providers that would have their own "canDelete" set to true?

yes, the derived data provide would set canDelete to true and not the parent data provider.

* Sets canDelete flag
*
* @param canDelete
* true if data provider can create a derived data provider

With this a data provider factory instance can advertise special
capabilities that can be applied for the given data provider.

This commit adds code for that and implements the "canCreate" and
"canDelete" capability. "canCreate" indicates that this instance
can create a derived data provider. Use the IDataProviderFactory method
getAdapter(ITmfDataProviderConfigurator.class) to obtains an instance of
ITmfDataProviderConfigurator. This interface has methods to get
List<ITmfConfigurationSourceType> describing the parameters needed to
create a derived data provider using method
ITmfDataProviderConfigurator#createDataProvider.

"canDelete" indicates a the data provider can be deleted using
method ITmfDataProviderConfigurator#deleteDataProviderDescriptor.
