Allow for the image to be run with the root user if desired, however
change to requiring setting of a variable to allow it to continue as it
may change ownership of files unexpectedly.
Additionally ensure that the workdir passed to docker matches the target
mount path used, in case the realpath to ${PWD} resolves to be different
to it's value resulting in the starting workdir being somewhere
different to the current path on the host.
Fixes: #1442
Move the vagrant-libvirt plugin into being combined directly with
vagrant which both prevents the plugin from being reinstalled by any
subsequent call to `vagrant plugin install <plugin>` and avoids the need
to create and manage symlinks to a /vagrant.d directory for boxes.
Switch from having all documentation contained within the README to
publishing a jekyll static site of documentation under github pages.
This allows for configuration and installation guides to be handled
separately to make for the relevant pieces to be in smaller chunks and
therefore easier to follow for users. Additionally a table of contents
can now be included in a left navigation section that ensures it should
be possible to quickly jump from the start to any section and back
again.
Include support for publishing previews and releases under separate
directories to allow for them to exist at the same time as the other
latest version of the documents.
The navigation section also includes support for accessing any of the
other versions published so that it easier to see what configuration
options exist for a given release. These will be published automatically
when releases are added.
