Uploading keys is erroring and I don't know why

$ colmena  upload-keys --on kif --impure -v

I wish I could share more information, I have really no clue what to do though :sweat:.

Note I'm running Colmena 2bd563e847817a3e96b2aa9932109c83bc64e566.

Currently Child process exited with error code errors do lack quite a bit of context to be more useful. Are the keys fetched from keyFiles or keyCommands? One way without modifying Colmena itself is to run it strace -f and find which child process is exiting with 255.

5432fe488ebec7ee30aaea5fb18a759e30e59612 added backtraces to the "Child process exited with error code" errors when the RUST_BACKTRACE=1 environment variable is present. The plan is to have more hierarchical error types so it's easier to find exactly where in the deployment flow an error occurred.
