Change default CONFIG_STRATEGY

Due to the fact COPY_ONCE is not how most people expect the container
to work, as well as causing additional delays in the reconfigure
process by needing to delete and recreate teh container, we should
default to COPY_ALWAYS. It is both how operators and deployers expect
things to work and allows a quick restart to pull in a new config.
