The group variables originally in ansible/group_vars/ were playbook
group variables, due to being adjacent to the playbooks. Typically they
provided default values for global variables in the all group, as well
as some more specific groups. This has worked fairly well, but results
in (at least) a couple of problems.

1. The default variable precedence rules mean that these playbook group
   variables have a higher precedence than inventory group variables
   (for a given group). This can make it challenging to override
   playbook group variables in the inventory in Kayobe configuration.

2. Any playbook run by Kayobe must be in the same directory as the
   playbook group variables in order to use them. Given that they
   include variables required for connectivity such as ansible_host and
   ansible_user, this is quite critical. For Kayobe custom playbooks, we
   work around this by symlinking to the group_vars directory from the
   directory containing the custom playbook. This is not an elegant
   workaround, and has assumptions about the relative paths of the
   Kayobe configuration and virtual environment in which Kayobe is
   installed.

Sets 'monasca_install_type: source' to remove need
for kolla-ansible var boilerplate.

Also use default Monasca parameters to configure
Grafana post deploy.

This is a minimal fix to support loading dashboards into the Monasca
Grafana fork. It firstly aligns the default Monasca Grafana control
plane organisation and Monasca Grafana local admin username with Kolla
Ansible to make the feature easier to use. Secondly, it extracts the
associated OpenStack project name from this variable by stripping off
the OpenStack domain.

Longer term we may wish to move the dashboard loading functionality into
Kolla Ansible, now that it supports deploying Monasca.

Affects Rocky onwards.

This add supports for running the stackhpc.grafana-conf Ansible
Galaxy role against a monitoring server to configure Grafana
post deployment. This includes:

* Creating an organisation
* Configuring dashboards for the organisation from a git repo
* Configuring datasources for the organisation
