Release v5.1.0

This release adds more customizability of the DNF conf through the mixer
command line, adds a --clean option and does not wipe the outputdir by default
when re-running a 'build' command for the same build number, switches to zstd
compression for delta packs, and adds misc fixes to internal code structure.
