Support user sorted lists

[alexandernorth]

There are some lists which we need to let the user define the sorting on, rather than ignore the parameter and do the default system sort in all cases.
We should support cases where the yang model defines a user ordering https://datatracker.ietf.org/doc/html/rfc7950#section-7.7.7

It could be worth looking at https://datatracker.ietf.org/doc/html/rfc8072 which defines operation patching with e.g. "before"/"after"
