As we start to ramp up work on this tool and the associated build image, we may encounter times where we add functionality to core in specific versions, but if users are still running old versions of core, and are consuming the bleeding edge version of the build image, this could cause issues.

We should build in some compatibility check that can check for the existence/value of an internal_system scoped variable LAGOON_SYSTEM_CORE_VERSION which core should/will pass through and we can use this to fail builds and alert users/lagoon administrators that they are running an out of date core for the build image in use.
