The resource version metrics expose the resource version as a string in the label.
This value can change often and would therefore create huge cardinality.
This changes is to be the number value of the metric itself instead.
- To allow other external Stores, remove the `FamilyByteSlicer` interface
and give access directly to `metric.Family`.
- Move functions present in `pkg/metric/generator.go` to a dedicated package
`generator` in `pkg/metric_generator/generator.go`.

Since the removal of collector, this introduces both the concept of the
store and the resources instead of collectors that the user passes in.
The user facing logs and flags were not changed as that would be a
regression.
