unify methods of rewriting event properties to match zino 1 protocol.

[runborg]

There are now two ways that event property-names are modified to match the zino 1 protocol names. the first one is a catch-all rewrite of underscore to dashes: 7caf880#diff-5eef89ad67750f4ac6ef25ea411553bf2bc5dab2d901020b7526ab52b774bf3b

and the new one is using aliasses in pydantic to create custom names as done here: #335

as there is also some case-sensitive property-names the first implementation does not fit all modifications, that should be removed and add pydantic aliasses to all properties that need a rewrite instead.

as for now it seems to be these elements needing to be rewritten to pydantic aliasses:

BGP:

• remote_addr: Optional[IPAddress] = None
• peer_uptime: Optional[int] = None

Alarm:

• alarm_type: Optional[AlarmType] = None
• alarm_count: Optional[int] = None

This issue merits a meeting about all the event/pm attribute names, to generally having better/more descriptive names and then adding the Zino1 names as alias.
