[TerryHowe]

What this PR does / why we need it:

The printer is supposed to be a very generic output object and this change moves in that direction.

@TerryHowe What kind of problem is expected to be resolved by this PR? Moving print-related utilities out of status folder is doable, but status package including the handlers should be placed side-by-side with metadata in the same folder level.

Types of output

• Status output of the operation
• Metadata output of the operation
• Content output (non-relevant to this PR)

Taking pull artifact as an example:

• Status output: progress bar
• Metadata output: showing what has been pulled (e.g. filename, digest ...)
• Content output: the artifact content save as a file (non-relevant to this PR)

I just created this PR to give better separation of concerns and avoid possible circular dependencies. The Printer is a like a logging system and really shouldn't be dependent on what it logs.

@TerryHowe Got it, then this PR should only move print.go and print_test.go
