HDDS-1627. Make the version of the used hadoop-runner configurable

[elek]

During an offline discussion with [~arp] and [~eyang] we agreed that it could be more safe to fix the tag of the used hadoop-runner images during the releases.

It also requires fix tags from hadoop-runner, but after that it's possible to use the fixed tags.

This patch makes it possible to define the required version/tag in pom.xml

1. the default hadoop-runner.version is added to all .env files during the build
2. If a variable is added to the .env, it can be used from docker-compose files AND can be overridden by environment variables (it makes it possible to define custom version during a local run)

See: https://issues.apache.org/jira/browse/HDDS-1627
