Add availability to hide spinner

[hackallcode]

In GitHub Actions on pack stage I have a spinner that makes such logs:

   • Building base image myapp-build

|
/
-
\
|
/
-
\
|
/
-
\
|

So, I want to disable the spinner in CI. Let's add a flag to do it.

Whether you'll be okay if we'll just fix its displaying? Or it looks so, when you write the log to a file?

Seems similar to #627.

It's not similar to #627.

You can just fix displaying, yes. For example, if the console doesn't support \r then hide spinner, but if supports then show it.

GH Actions doesn't support \r, so we can see hundreds of spinner lines instead of one line.

Could it just check if the shell is non-interactive and turn off the spinner?

If it works in GH Actions, it's ok
