This is consistent with what all other roles do. If someone includes a
role, the assumption is that they want its functionality enabled.
The playbook distribution then disables components via
`group_vars/matrix_servers`. We've always had `matrix_grafana_enabled: false`
there, so flipping the in-role `_enabled` flag to `true` does not change
anything for playbook users. Users who import the roles individually in
their own other playbooks (and who don't use `group_vars/matrix_servers`)
may observe a change in the defaults with this.
Using `matrix_synapse_*` variables within the `matrix-grafana` role
is not a good practice.
We now have a `matrix_grafana_default_home_dashboard_path` variable
with a good universal default value and we override it via
`group_vars/matrix_servers` based on enabled components, etc.
This is a better fix for https://github.com/spantaleev/matrix-docker-ansible-deploy/pull/2133
We shouldn't be using it in the role (`tasks/setup.yml`) without
defining at least some default value in the role itself.
We've always had the override in `group_vars/matrix_servers`,
so the variable was essentially defined (at the playbook level), but
that's not the right way to do things.

This keeps the configuration cleaner and hopefully prevents odd issues
if Synapse (by any chance) happens to interpret `pusher_instances: []`
as "no pushers", instead of as "push from the master process".
I haven't confirmed what an empty pushers/federation-senders list means,
so it's safer to just avoid it.
As stream writer workers are also powered by the `generic_worker`
Synapse app, this necessitated that we provide means for distinguishing
between them and regular `generic_workers`.
I've also taken the time to optimize nginx configuration generation
(more Jinja2 macro usage, less duplication).
Worker names have also changed.
Workers are now named sequentially like this:
- `matrix-synapse-worker-0-generic`
- `matrix-synapse-worker-1-stream-writer-typing`
- `matrix-synapse-worker-2-pusher`
instead of `matrix-synapse-worker_generic_worker-18111` (indexed with a
port number).
People who modify `matrix_synapse_workers_enabled_list` directly will
need to adjust their configuration.
