In order to make it easier to detect the currently deployed
venv for a service, and therefore allow smarter decisions
for things like upgrading, we implement the venv tag as a
local fact.
The file used to store facts will be the same for all
OpenStack services, with each service using its own section.
Example:
"ansible_local": {
"openstack_ansible": {
"keystone": {
"venv_tag": "14.2.1"
}
}
}
