`asw ecr get-login` includes deprecated Docker flag

[drewandersen]

Execute aws ecr get-login --region=us-west-2 and receive the following error:

unknown shorthand flag: 'e' in -e
See 'docker login --help'.

The email flag was removed in release 17.06.0-ce: docker/cli#143

You can remove that by specifying the --no-include-email flag. We default to including the email so we don't break customers still relying on it.

Duplicate of #2732, #2694, #2691, #2676, and a few others
