Progress bars must go to stderr, not stdout

[fernando-villalba]

Issue

Progress bars should not be going to stdout, they need to go to stdout

How to replicate

1. Run a command with the --wait flag and pipe the output to a file

civo bucket create --wait -o json test-bucket > test

2. Inspect the file we just created:

cat test

Output:

% cat test
{"access_key":"xx","id":"9076386c-eda9-4eab-a995-7ba1aa92d3a5","name":"test-bucket"}

Looks normal? Except that it isn't, for example try the following command:

jq -r .access_key < test

Output:

tempo-tutorial % jq -r .access_key < test
jq: parse error: Invalid numeric literal at line 1, column 3

That should no possible? Why is this command not working in this perfectly valid json?

Because of the non-printable characters

3. Inspect the file for non printable characters

cat -v test

output:

 % cat -v test

Aceptance Criteria

• Send the progress bar to stderr.
• Consider having a global --silent flag for this type of output. There are situations, such as scripts where the user may want to silence this output. Sending it to stderr makes this a lot easier though, so this second part is not strictly needed
