kustomize lookup plugin: build_flags

[eb4x]

Allow setting a string of optional build_flags at the end of the command.

SUMMARY

A string to add some params/options to the end of "kustomize build dir" / "kubectl kustomize dir" command. This could have been a list, or some other grandiose parsing event, I haven't put much thought into other use-cases.

COMPONENT NAME

kustomize lookup plugin

ADDITIONAL INFORMATION

It feels like a one-off kind of thing, where I just need to add "--enable-alpha-plugins" at the end. Maybe someone else will end up in a similar predicament later down the line, and be relieved that they can just build_flags="--all-my great --build-options are-available --yay".
