Version inconsistencies

[mike-es]

The versions listed on hub.docker.com (tags), github.com (releases), and in the code itself (Dockerfile) don't seem to line up.

Docker Hub
latest/master: pg_prometheus 0.0.1, timescaledb 0.7.0, postgresql 9.6

If pg_prometheus 0.1 is released and stable I would expect "latest" to point to this version. It seems like this tag wasn't created with the Makefile since latest/master/commit are not updated.

Github
latest (only) release: pg_prometheus 0.1 (?), timescaledb 0.8.0, postgresql 10.2

This release seems ok except for the Dockerfile (see next section).

Dockerfile
master branch: pg_prometheus 0.0.1, timescaledb 0.8.0, postgresql 10.2

Even though the latest released version is pg_prometheus 0.1 the Dockerfile has "ENV PG_PROMETHEUS_VERSION 0.0.1"
