create a pkg/cliprint package

[ilgooz]

This packet should manage clispinner as well as printing something to the stdout(can be customized). This way it can stop the spinner before printing persistent text.

This will also fix this concurrency issue: Sometimes when you fmt.Println, it gets printed before the events are printed in the pipeline. cliprint, will do some sort of queue by using a channel to print events or fmt.Printlns (generics can be used for the channel type to support both kind)

This package have a much bigger scope than just a concurrency problem. We already have a few issues for cli output improvement #1079, #1982, #2060 . I consider to make this issue a place to discuss ideas about a new cli output package.

Move concurrency bug to another issue #2391
