[FR] All Models should have Metadata attached

Please verify that this feature request has NOT been suggested before.

• I checked and didn't find similar feature request

Problem statement

I have some ideas of things I would like to implement in some plugin/using my own API scripts. However, the central models are missing the Metadata extension in several cases.

Suggested solution

Add the Metadata plugin to the Models missing it. See PR #3895 as a reference.

Already present:

• Company
• PO
• SO
• Part categories
• Part
• Stock item
• Stock location

Not present yet:

• Manufacturer part
• Supplier part
• Part labels
• Stock item labels
• Stock location labels
• PO lines
• PO extra lines
• SO lines
• SO extra lines
• SO shipments
• Build Orders
• Build order items
• BOM items
• Part category parameter templates
• Reports BOM
• Reports Build
• Reports PO
• Reports SO
• Reports test
• Stock item test results
• various attachments
• Part parameters
• Part relateds

No action on these:

• Users
• Part pricings
• various price breaks

Input welcome - which ones make sense? Did I miss any which have had metadata models added since 0.9.2?
