[2.0] Fixed issue with Cache drivers that in some situations they were not storing the entries. Also fixed bug with queryCacheTTL that was not being considered in a Query.

[2.0] Refactoring code for reading multiple sources of mapping information from ClassMetadataExporter to a new ClassMetadataReader tool so it can be used to read mapping information easily from multiple different sources. This is used for generating repositories, converting mapping information, generating entity stubs, etc. Generally though, it is useful to be able to read the information for some mapping files into an array of ClassMetadataInfo instances without it being bound to the ORM and the metadata referenced by the EntityManager ClassMetadataFactory

[2.0] Extracting Doctrine 1 schema conversion from orm:convert-mapping task to a orm:convert-d1-schema task

[2.0][DDC-426] Fixed issue with CliController that never notifies if run() executed successfully or not.
