Ian Wienand 7602343b6a nodepool-elements: Use venv for utilities
Since all platforms have Python 3, use the new ensure-venv element
from the dependent change to install bindep and os-testr.

Since we are no longer using pip to install anything during the
builder, this drops the dependency on pip-and-virtualenv from
nodepool-base.  Avoiding this element is our long-term goal, as it's
modification to system state are problematic in a number of ways.  To
maintain the status-quo, the pip-and-virtualenv element is added
explicitly to each build's element list, with a note on it's future.

The current plan for backwards compatability is to replicate the
environment pip-and-virtualenv provides in a base role/job that can be
optionally included.  To test this, provide a new node type
"ubuntu-bionic-plain" that will not include the pip-and-virtualenv
element.  This is put on just one provider (rax) to minimise impact.

The dependent-change (and a dib release) is required before merge so
the ensure-venv element is available.

nodepool-base

Tasks to deal with image metadata and other Nodepool cloud specific tweaks.

Name resolution

The image should have the unbound DNS resolver package installed, the nodepool-base element then configures it to forward DNS queries to:

NODEPOOL_STATIC_NAMESERVER_V4, default: 1.0.0.1 NODEPOOL_STATIC_NAMESERVER_V4_FALLBACK, default: 8.8.8.8.

If NODEPOOL_STATIC_NAMESERVER_POPULATE_IPV6 is set to 1 then the following two servers will be configured as forwarders too

NODEPOOL_STATIC_NAMESERVER_V6, default: 2606:4700:4700::1111 NODEPOOL_STATIC_NAMESERVER_V6_FALLBACK, default: 2001:4860:4860::8888

Note externally setting either of these values implies NODEPOOL_STATIC_NAMESERVER_POPULATE_IPV6=1
