Fix #117 - Add longer health check timeout on register-buddy container

[nicko170]

Australia is a loooong way away from hub.docker.com, which causes the register-buddy sidecar to constantly crash as seen in #117. Every request to /healthz calls the external API service before responding, and 1 second timeout is simply not enough time.

Adding a 3 second check timeout here fixes the issue, vs the default liveness check timeout of 1 second.
