deltas: Improved message returned when delta is too big

[gsilvapt]

Improved the big delta warning/error message when the user is trying to push changes, making it display the size of the delta before pushing the full snap.

Thanks @gsilvapt. Some missing things here:

• You need to sign the license agreement: https://www.ubuntu.com/legal/contributors
• You have a static error:
  snapcraft/internal/deltas/errors.py:43:1: E302 expected 2 blank lines, found 1

Thanks for reviewing this PR, @ElOpio.

I've signed the license agreement. Never saw this step before :)

What can I do about the static error? Judging the return output, I can simply add the line missing?

[come-maiz]

yes, you are missing one empty line.

[gsilvapt]

I didn't notice Sergio had merged to the master, so I had this extra commit 55ad8bc which is the same update. Hopefully this is all good now.

Thanks @gsilvapt!
@kyrofa or @kalikiana, please make the second review here.

[kyrofa]

This is excellent, thank you!

@gsilvapt it seems you made your email private in github, and that makes the automatic CLA check to fail because it can't find your email.

@ElOpio I've made it public as of now. Sorry. :-)
