[Feature] Customize context file name

[Hedi-s]

Is your feature request related to a problem? Please describe.
I am using a script to do few things that couldn't be done by the scaffolding.
I just discovered this project which covers everything except for the context file name.
On my current project the generated files name are like ContextName.generated.cs or EntityName.generated.cs.
We can customize entities file name with the entityFileNameTransformer but not for the context.

Describe the solution you'd like
I would like to add a contextFileNameTransformer to handle context file name.
