Backend-agnostic APIs for customization

[moe-ad]

Currently, backend customization by a consuming library requires direct coupling with the backend. A very important value-add the visualization interface could bring to consuming libraries is providing some common backend-agnostic customization APIs via a higher level interface like the Plotter class. That way:

• library-specific customization is programmed to this interface and backends can be easily swapped.
• adding a new backend means consuming libraries automatically supports it without the need to add more code.

This issue has been created to start discussions regarding customization APIs that are useful across PyAnsys libraries using the visualization interface.

We can start by discussing simple ones for:

• adding points
• adding lines
• adding planes
• adding text at a specific location

Yes agreed - I also experienced the same in Geometry. Let's talk about this with @moe-ad, @AlejandroFernandezLuces

Thanks @moe-ad! One I personally would like to use is the capability to add custom labels to specific nodes or elements, like let's say the value at that node.
