Stackable Config / Overwrites

[pauxus]

Allow multiple, overriding configurations.
I.e. basic configuration, with specific configuration overriding some values (for example helm value files)

This could be handled by using templates -> check for template handling of nested objects

Perhaps a new Factory method like X.Create.From(A, B, C)

[pauxus]

Not templates, but copyFrom should be sufficient.
One thing open:

• Lists add or replace (compare to helm)
• Map add or replace
• Null Values (i.e. override values with null)
