Add progress bars for stages / items

[detjensrobert]

Having progress bars for build progress, upload progress, and deploy progress will make things much slicker and obvious to what we are doing when there is no output.

https://lib.rs/crates/indicatif integrates with tracing nicely and won't clobber the log output. If we set up tracing spans, we might also get progress spinners for basically free.

Some concepts:

Cant really get good progress indication out of the docker build without parsing the log output, so probably spinners for this

[INFO] whatever log output up here...
[INFO] not blocked by the progress bar
Building images [=========>               ] 4/12 images
\ misc/garf building...

/ pwn/notsh pushing registry.example/chals/pwn/notsh:testing...

File uploads ez progress.

Uploading assets [===============>        ] 13/20 files

pwn/notsh libc.so [====>                 ] 15Ki/100Mi

Apply kube resources also doesnt really have enough steps to have a bar, so spinners again probably.
