Implement "quiet mode"
This change adds a "--quiet" startup option, which causes Blaze not to print any status messages, progress messages, info messages or warnings of any kind. Error messages are still emitted as usual.
Fixes #4867.
RELNOTES[NEW]: The "blaze --quiet" command line option can now be used to make Blaze emit much less output.
