Feature
Ability to add extra properties to columns - technical properties (fixed) and custom properties (variable)

Describe the task
It is great that the columns have the properties - name, type, description, tags and glossary terms displayed on the table schema view.

It would be really great to get a separate page to drill down on the column level to get more information on the column. One such use case would be for SAP experts that need to check more meta information on the column and also assign custom properties on the column level to do filtering or impact analysis and much more.

There can be close to 100,000 SAP business objects tables that need to be tracked on OM and without these extra technical properties it is hard to make sense of cryptic sap names.

A simple example would look like the following,

Note: Business properties are already custom properties feature of OpenMetadata.
