[RFE] Make SUPPORTED array in config.py more adaptable

[sadsfae]

Currently we have to define supported Dell systems so that the Badfish library in QUADS knows to do special things that Dell is capable of during the M&R QUADS Phase:

https://github.com/redhat-performance/quads/blob/latest/src/quads/config.py#L86

This is referenced here:

https://github.com/redhat-performance/quads/blob/latest/src/quads/helpers/utils.py#L10

and then M&R decides which hosts to action as Dell systems or not here:

https://github.com/redhat-performance/quads/blob/latest/src/quads/tools/move_and_rebuild.py#L189

Solution

Let's pull the SUPPORTED array out of config.py and into it's own /opt/quads/conf/dell_models.py

Why

• users would have to modify this to add their own Dell models here, requiring them to edit RPM-managed codebase files.
• if it's kept in its own configuration file we can use %config noreplace in the packaging so what users add isn't overwritten

Discussing this more with @grafuls the ideal solution is to simply just gate on Dell vendor:

https://github.com/redhat-performance/quads/blob/latest/src/quads/config.py#L86

This way we won't have to keep expanding this model list nor have to worry about having to match if a user uses a different variation or sub-variation, all we care about is if it's a Dell or not. If it doesn't work it means we don't have that model either and we can turn that into an RFE for Badfish to support it.
