There's no service information during fuel-master node installation.

Steps to reproduce:
1) Start Fuel installation
2) Wait for Fuel menu is shown
3) Press F8 to continue installation
4) "Total time:" message appears in the console

Actual result: the installation process continues for 20-30 minutes (depends on host machine)

Expected result: information about installation process is being shown, for instance current operation, estimated time etc.

It is related to UX of MOS, so increase to High.

Added version.

The reason is that Docker doesn't display a progress bar of loading images from the tarball[1][2]. The only solution at the moment is to use pv[3] to pipe the data to Docker.

Fix proposed to branch: master
Review: https://review.openstack.org/170153

[Maciej Kwiek (maciej-iai)]

After testing it appears that pv is useless in this use case. `Docker load` command loads the image tarball at the beginning of it's runtime, which happens quite fast and then it makes it's own processing, which doesn't involve any IO for the most time (therefore -d option for pv is useless too). I proposed a fix which was the initial idea - split the message so that after the lrzip executes, there is a message stating "This will take a while".

If we are ever going to show real progress bar to the user, the change to docker load command will be needed. Another workaround would be creating docker registry and loading the image by docker pull instead of docker load, but that doesn't really make much sense in any other way and seems to hacky for my taste.

    Split message about unpacking and loading images

    User could think that master node installation hanged, as lrzip provided
    total time and nothing happened next. After lrzip executes there is
    additional message warning that image loading may take some time.

    PipeViewer was thought of as possible mean to show progress bar to the
    user, but because of the way `docker load` command works (it loads the
    data first and then processes it) it wasn't a viable option.

    To assure good user experience docker load should provide it's own
    progress bar or any other indicator, but this change would need to be
    made in docker itself.
