gerrit upgrade - Oct 18, 2018

[Kelley Spoon]

Hello All,

Due to a security vulnerability, we need to upgrade gerrit from the current
2.15.3 release to 2.15.5. The upgrade will take place tonight around 8pm
UTC. No extended downtime is expected but there will be a brief
interruption in service due the server being restarted.

Let me know if you have any questions or concerns.

Thanks,
