This commit also fixes some minor typos, adds doc comments
and moves some higher-level definitions into bpcore since
v2 will probably make use of those as well.

This reverts commit 060654f.

This import was meant to compile as-is but some changes were necessary
to make it compile without domain or kubernetes package references. Long
story short, I needed to change a lot of things

This was changed during the extraction and was most likely a mistake.
The original code used string here.

Somehow these functions seem to be necessary by the blueprint operator's
deep copy generator even though I do not see where I might have deleted
it

In package names v1/v2/v${nonzerointeger} is reserved to identify module
versions. This was not the case of the previous state but rather the
version of the blueprint implementation.

This commit removes this misnaming towards json to amend the situation
above and also to put the focus on the format being worked on.

The kubernetes implementation Blueprint v2 was moved into its own
library k8s-blueprint-lib because there would be even more changes with
way more k8s resources and logic attached. These two functionalities
should not mix different libraries and possibly attach to another's core
entities.
