From: ZheNing Hu <adlternative@xxxxxxxxx>
Sometimes when users use scalar to download a monorepo
with a long commit history, they want to check the
progress bar to know how long they still need to wait
during the fetch process, but scalar suppresses this
output by default.
So let's check whether scalar stderr refer to a terminal,
if so, show progress, otherwise disable it.

scalar: show progress if stderr refer to a terminal
When users use scalar to download a monorepo with a long commit history
(or the client and server network communication is very poor), we often
need to spend a long time in the fetch phase of scalar, some users may
want to check this progress bar To understand the progress of fetch and
how long they have to wait, so we should enable scalar to display fetch
progress.
v1. add [--verbose| -v] to scalar clone.
v2.
1. remove --verbose option.
2. check if scalar stderr refer to terminal, if so, show progress.
v3.
1. fix some tests suggested by Derrick Stolee.
Note: output look like this:
$ scalar clone git@xxxxxxxxxx:git/git.git

branch 'master' set up to track 'origin/master'.
Switched to a new branch 'master'
Your branch is up to date with 'origin/master'.
"new branch", "new tag" output is a bit annoying, it would be better to
suppress them, but keep the progress.
