Verbose option for cli push command

[ynie]

Is your feature request related to a problem? Please describe.
I'm not sure why each upload takes ~5 mins since I should only have python files. I suspect some of the unintended larger bin files are being uploaded as well. It would be nice to see what are the files being uploaded to the server.

Describe the solution you'd like
truss push --verbose
It prints out all the files being included in the zip file. Maybe output the file zip file location as well?

Describe alternatives you've considered
Warning for any files larger than 1mb.

Additional context
None. Thanks!
