Align module names for consistency

[patchwork01]

Background

Following up from:

• Issue 3501 - Adding structure for Bulk Export #3540 (comment)

Description

We'd like to align the naming of modules in the project to be more consistent.

Analysis

The bulk-import-common module seems more appropriately named as bulk-import-core, since its only dependencies are core modules. The package naming in that module is also not consistent with the name of the module.

We can check other modules for consistent naming and package naming.
