feat: public methods for the upgrade, Unbound forwards and OSPF (0.4.0)

netOrk reached these through the private _get/_post (netOrk #1113); they
are napalm-device-types 4.17's contracts now:

- apply_updates passes the packages it is given (it dropped them) and
  get_update_progress reports the upgrade's state and log.
- get_dns_forwards, set_dns_forward (an existing forward of the domain
  is changed, not doubled) and remove_dns_forward, each applied with a
  reconfigure; a refusal is raised.
- get_ospf translates FRR's diagnostics into neutral terms.

Requires napalm-device-types 4.17.0.
