Reuse service id for patch

[congwang09]

Relates to: #238, #235

Add a MongoDB collection "historical_connections" for saving the historical connections. Use service_id as key, a list of connection json as value. Example:

'e7fdf472-547d-455c-9c5c-b49c0a0d2974': ['{"name": "VLAN between AMPATH/300 and TENET/300", "endpoints": [{"id": "urn:sdx:port:ampath.net:Novi03:1", "name": "urn:sdx:port:ampath.net:Novi03:1", "vlan_range": 300}, {"id": "urn:sdx:port:tenet.ac.za:Novi07:1", "name": "urn:sdx:port:tenet.ac.za:Novi07:1", "vlan_range": 300}], "id": "e7fdf472-547d-455c-9c5c-b49c0a0d2974"}', '{"name": "VLAN between AMPATH/300 and TENET/300", "endpoints": [{"id": "urn:sdx:port:ampath.net:Novi03:1", "name": "urn:sdx:port:ampath.net:Novi03:1", "vlan_range": 300}, {"id": "urn:sdx:port:tenet.ac.za:Novi07:1", "name": "urn:sdx:port:tenet.ac.za:Novi07:1", "vlan_range": 300}], "id": "e7fdf472-547d-455c-9c5c-b49c0a0d2974"}']

And enable using same service_id when doing PATCH

For historical records: they might ask for timestamp information, ie, when the event happened. Just a note for future action....

That's a great point, updated to include a timestamp in seconds. It's like this now:
