[Task]: harmonize the ActionMeta and TransformMeta classes

[bamaer]

What needs to happen?

even though Transforms and Actions are different objects in Apache Hop, they have a number of similarities that should be reflected in the code. For example:

• there's a TransformMeta.getTypeId() that doesn't exist in ActionMeta
• there's a ActionMeta.getTypeDesc() that doesn't exist in TransformMeta
• TransformMeta.getPluginId() vs ActionMeta.getAction().getPluginId()

Issue Priority

Priority: 3

Issue Component

Component: Actions, Component: API, Component: Transforms

[nadment]

Need for harmonization too:

• TransformMeta.getTransformPluginId()
