Changes:

• Updating Traefik to v2.10.0
• Printing the push filesize before deploy to avoid pushing of large images
• Adds emojis to the client output makes it distinguishable from server output.

Instead of adding rich as a dependency, just to print a few emojis, let's just add in the emojis directly (its just unicode, you can copy-paste them in the messages in the source).

>>> import rich
>>> rich.print(":x::information_source::heavy_check_mark:")
