easy_install doesn't exist in 18.04

[Nick Wilburn]

Kolla Version: 7.0.1
Install Type: Binary
Distro: Ubuntu 18.04

I am going through a kolla-ansible all-in-one installation following the documentation listed here: https://docs.openstack.org/kolla-ansible/latest/user/quickstart.html

Running kolla-ansible -i ./all-in-one bootstrap-servers will error out in the baremetal role here: https://github.com/openstack/kolla-ansible/blob/master/ansible/roles/baremetal/tasks/install.yml#L110

The easy_install task errors out on ubuntu18.04 because easy_install isn't install-able in Ubuntu 18.04 see here: https://bugs.launchpad.net/ubuntu/+source/python-setuptools/+bug/1774419

There are several workarounds while this bug is still open which I think should be applied. Currently the installation does not work without modifying the role which feels very dirty and offputting.

1) Check for the existence of Pip and document its requirement before installation. If pip exists we don't need easy_install to download it and we can proceed. If it doesn't we can error out with a helpful error message.

2) Install pip directly using `curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py`
This is less optimal as it obviously won't work for offline environments. We could allow the configuration of a "get-pip" URL which would default to bootstrap.pypa.io, but it would be easier to just use option #1.

I'm more than happy to make a PR for either of these options. Please let me know your thoughts.

We used the following workaround, yes it's a matter of changing in the baremetal role tasks (quick n dirty). We're also running version 7.0.1 of kolla-ansible and have tried to deploy new compute hosts on 18.04.

Besides hitting and backporting the fix for this bug: https://bugs.launchpad.net/kolla-ansible/+bug/1791355, we did the following:

1. Removed the "Install pip" task in baremetal/tasks/install.yml
2. Added "python-pip" package to debian_pkg_install in baremetal/defaults/main.yml

I also encountered this bug on my Ubuntu 18 and what I did was change "easy_install" to "package" on the baremetal role.

[Igor D.C. (igordc)]

Ubuntu 18.04 here, same issue. Using "package" didn't solve it for me though, as it failed for a different reason. Instead, I used "pip" instead of "easy_install".

[Mark Goddard (mgoddard)]

I proposed this as a solution: https://review.openstack.org/651136

It installs the python-pip package and skips easy_install task on ubuntu 18.04+.

    Don't use easy_install on Ubuntu 18+

    Currently easy_install is not available on Ubuntu 18+ due to [1]. In
    that case, install pip via apt rather than easy_install.
