Newly built Patroni images will not run #692
Description
Is your feature request related to a problem? Please describe.
The apps/pgsql/patroni/docker/Dockerfile builds using the latest from zalando/patroni, which is currently v1.6.5. The bcgov image was originally built with v1.5.5, which is seven releases older.
Doing a new build with v1.6.5 causes the following error at runtime:
Readiness probe failed: 2020-05-27 21:53:00,958 - WARNING - /usr/local/lib/python3.5/dist-packages/requests/__init__.py:91: RequestsDependencyWarning: urllib3 (1.19.1) or chardet (3.0.4) doesn't match a supported version! RequestsDependencyWarning)
If the above error is fixed, the master pod will still not pass health checks, since patronictl list now only provides Lag in MB for replicas.
Definition of Done
An image built with Patroni v1.6.5 (the current latest) should start in pods without error.
