Description

Currently I see at least 3 places where we have to deal with table destruction:

1. unregisterCache() -> Schema.onDrop()
2. unregisterType() -> removeTable()
3. stop()

We need to refactor them to call the same logic which has to always do the following steps:
1. dataTables.remove()
2. GridH2Table.destroy()
3. U.closeQuiet(TableDescriptor.luceneIdx)
