- introduce install_packages(..., chain=True) to allow chaining on
onto existing RUN commands
- introduce install_packages(..., clean) which defaults correctly
but allows you to override if you want to avoid doing extra
package manager cleanup
- refactored several calls in base to make use of these new features
In general this allows for macros.install_packages to be chained
after other calls
for example
RUN foo && {{ macros.install_packages(..., chain=True) }}
