Description

See the attached PDF.

Currently there is a lot of overlap with the entity model classes. All the entity model classes in the code are are prefixed with "M" and are under the org.apache.sqoop.model package.

The proposed refactoring will do the following things.

No more MConnectionForms and MJobForms
MConfig( abstract)
FromConfig ( may or may not inherit MConfigList). Still debating if we need a conflg list. We can use a group attribute on the inputs if we need add hierarchy to the config inputs
ToConfig
DriverConfig

FromConfig/ToConfig/DriverConfig entities belongs to a MJob
MInput (MConfig has one or more MInputs)

MConnector will be pretty dumb and will hold its 3 config objects, LinkConfig. FromConfig and ToConfig
MLink belongs to a MConnector
MLink will have a reference to connector and the link config. There will be no connector/ framework part.
MSubmisssion belongs to a MJob

Lastly, the Repository schema will also be renamed to reflect the context/link/driver/jobrun changes

End of Story!
