feat: use shorter instance uri when logging

[kurtisvg]

Change Description

Uses "project.region.cluster.instance" instead of the full instance URI when logging for a more compact reference.

example:

2022/12/13 23:27:56 [proj.region.clust.inst] client closed the connection
2022/12/13 23:27:56 [proj.region.clust.inst] Listening on 127.0.0.1:5000
2022/12/13 23:27:56 [proj.region.clust.inst1] Listening on 127.0.0.1:6000
2022/12/13 23:27:56 [proj.region.clust.inst2] Listening on 127.0.0.1:6001

Depends on #210
