Package ioutils: - remove file progress from ioutils and rework it to package file/progress Package file/progress: - simplify call / use of file progress - optimize code - use atomic to function progress - isolation part of code - make interface more compatible with *os/File / io interface Package archive/gzipreader - create package to expose a io.reader interface from a no gzipped io.reader - add interface GZipReader to expose metrics like rate of compression Package archive: - apply following change - add minor internal change into errors files Package artifact: - apply following change - add minor internal change into errors files Package aws: - apply following change - removing minio server from repo Package mail: - apply following change - add minor internal change into errors files Package nutsdb: - apply following change - add minor internal change into errors files Package static: - apply following change Other: - bump dependencies - ci/cd : add a wget command to dl minio server for testing - add aws/minio to gitignore
