examplegen is a tool that generates examples for manifest objects.
These examples are usually stored in the examples directory of
the respective object's package or in the object's package directory itself
inside examples.yaml file.
Each object can have its variants and sub-variants.
Example of such distinction for SLO is Prometheus based SLO with
calendar aligned time window.
Prometheus will be the variant and calendar aligned time window
will be the sub-variant.
