Questions on the list of tiebreakers defined in RFC8776

[italobusi]

The model provides a list of tiebreaker criteria "to apply on an equally favored set of paths, in order to pick the best".

Few questions for clarification:

1. The tiebreaker-type is an identityref with base path-metric-type and not with base path-tiebreaker-type

2. Is the list ordered or not? If ordered, how? If not, how different tiebreakers can be applied?

Note that RFC8776 defines the path-tiebreaker-type base identity and its derived identities but no data node using them.

Split into two issues:

• Allow both using both tiebreaker types (e.g., min-fill, max-fill) and path metrics as tiebreakers #265
• Add ordered-by-user statement to the tiebreakers list #266
