TablePanel: POC of custom cell rendering from plugins

[torkelo]

This is a POC of how we can allow plugins to do custom cell rendering.

Scenarios

• Render a cell with some complex coloring/display logic that depend on some other cell or data
• Render an image before the cell text value (and image based on some cell value / lookup)
• Other custom cell renderings

Implementation problems

• My first approach was just allowing a full custom CellComponent (IE similar to how DefaultCell, and BarGaugeCell are implemented) but this is really problematic as those cells require a lot of Table internals to get cell position and styles. Maybe the cellProps is not that bad but exposing TableStyles and buildCellContainerStyle fee. very fragile. So instead I explored a custom cell rendering that still uses DefaultCell to handle data links and the position and padding of the cell, this limits custom cell renderings to not be able to do some things that require changing the styles of the cell container. But I think this limitation could be fine.
• Second problem is what the interface / props should be for the custom cell renderer in order not to expose to many internal table interfaces and types.

field & value maybe be enough. Can use a transformer to pass what's needed as a value
