action: ostree-commit: add Collection ID and Refs binding

This change adds metadata information into commit:
`ostree.collection-binding` and `ostree.ref-binding`.

Parameter `collection-id` allows bindings to collection refs
(collection id + branches). Ref bindings could be added with parameter
`ref-binding`. For Collection ID the branch name is used implicitly in
case if `ref-binding` list is empty.

Requires libostree minimal version 2018.6.
