kuda dev doesn't work with remote deployer

[cyrildiagne]

kuda dev is not yet supported by the remote deployer. Implementing it requires a few things.

Deployer:

• [ ] start skaffold dev and send back dev pod & container ids
• [ ] listen for new uploads with these dev pods & container ids
• [ ] upload files to pods at the right location

CLI:

• [ ] stream logs
• [ ] watch local changes in goroutine
• [ ] add changed files to tar & send tar to deployer with
