print everything except progress in non-terminal

Instead of only checking `Progress != nil` (which is always true because
the server sends `"progressDetail":{}` when it doesnt have the progress), we
also check if `Progress.String() != ""`, which should be sufficient to filter
out the progress data.

LXC TEMPLATE WILL CREATE MOUNT

Lxc driver was throwing errors for mounts where the mount point does not exist in the container.
This adds a create=dir/file mount option to the lxc template, to alleviate this issue.

Corrected description of --sig-proxy

Signal proxy does work only in non-TTY mode (--tty=false). Man pages and
commands should not lie about it.

Be clearer in docs about COPY/ADD dirs
COPY/ADD just copies the contents of dirs, not dirs themselves.
This PR tries to clear that up in the docs.

Closes #8775

Make sure integration-cli test clean up

Common patterns:
- Multiple images were built with same name but only one cleanup.
- Containers were deleted after images.
- Images not removed after retagging.
