Package AWS:

- rework MultipartUpload process & helper
- update test to use lib size
- update object multipart to use new helper

Package IO Utils :
- add truncate & sync to FileProgress
- fix error on open file mode for FileProgress

Package Console :
- fix interface used for color buffer

Package Cobra :
- add function to print message on write config to use custom message instead of internal message. If the function is not set, the default message will be print.

Other:
- fix golangci-lint config to remove crazy linter (use only golang group compliance linter)
- bump dependencies
