Fix ansible-sshd version

The role ansible-sshd has removed existing tags and replaced them
with equivalents in a different format, e.g. 0.4.5 with v0.4.5, [1].
This is causing a failure when attempting to install the role defined
in this repository.

In order to help get this through the gate, we also disable nested virt
when in OpenStack-CI due to issues at some providers, as was done in
Ifae3425b66254aa655df5b6bb95896da1cccc32a and we ensure that tests in
OpenStack-CI make use of the reverse proxy, as was done in
