feature: progress bar for kit s over SSH

[0x70b1a5]

Is your feature request related to a problem? Please describe.
On slow connections,kit s can take a while to upload large packages. Sometimes it's unclear why the command takes so long to complete.

Describe the solution you'd like
An upload progress bar would unambiguously indicate that bandwidth was the blocker.

Describe alternatives you've considered
Waiting :)

Good idea. Looks like there are some good options out there such as indicatif, progress-bar, and pbr. I'll think about where else we could add useful indicators like this.
