Yannis Zarkadas a502717460 Make ordering configurable (#4019)
* api: Add new types for customizeable resource ordering

* plugins: Implement SortOrderTransformer plugin

Implement the SortOrderTransformer plugin. This plugin allows the user
to customize the order that kustomize will output resources in.

The API for the plugin is the following:

sortOptions:
  order: legacy | fifo
  legacySortOptions:
    orderFirst:
    - {GVK}
    orderLast:
    - {GVK}

* plugins: Add boilerplate and generate code for new SortOrderTransformer

* build: Add option to denote if the reorder flag was set by the user

We want to take different actions if the reorder flag was set by the
user or filled by the default value. Thus, we propagate this information
from build to the krusty options.

* api/krusty: Ensure sort ordering works with CLI flag and kustomization

Sort order can be defined in two places:
- (new) kustomization file
- (old) CLI flag
We want the kustomization file to take precedence over the CLI flag.

Eventually, we may want to move away from having a CLI flag altogether:
https://github.com/kubernetes-sigs/kustomize/issues/3947

Case 1: Sort order set in kustomization file AND in CLI flag.
Print a warning and let the kustomization file take precedence.

Case 2: Sort order set in CLI flag only or not at all.
Follow the CLI flag (defaults to legacy) and reorder at the end.

Case 3: Sort order set in kustomization file only.
Simply build the kustomization.
