Create a docker build environment that uses the minimum supported language levels

Following documentation of the supported language versions, we need to ensure there is a CI job that will build and run all the unit tests for all the minimum supported language levels.

Some examples of non-conformance right now:

ubuntu-trusty has perl 5.18.2 and xenial has 5.22.0, however all perl files state minimum of 5.10, so we should be building with 5.10 or move the minimum supported version up to 5.18.2.
