Add dashboard enhancements for new inputs and fix dashboard bug.

Had bug where normal jinja template context vars have same syntax as
grafana variable syntax ("{{ var }}"). Replace it with << >> and stole
render_custom() function from grafana to accommodate this requirement.
Also implemented various rows, graphs (/proc/vmstat info, interrupts, and
nstat info), and other fixes (e.g. missing filter on selected hosts).

Add grafana dashboard interface to publish telegraf dashboard.

This commit focuses on integrating the telegraf dashboard into the charm. Previously,
this existed in the grafana charm itself. The charm now uses the grafana-dashboard
interface to register its dashboard into grafana. A new config option is added as well
to specify the prometheus datasource (usually the prometheus application name). The
interface used to interface with Prometheus needs to be fleshed out more to allow for
automatic population of datasource as well as customizing the dashboard based on
metrics.

- add grafana-dashboard to metadata.yaml and layer.yaml as provider
- add leadership layer to handle leadership specific hooks
- implement prometheus_datasource config option
- add prometheus-client.configured flag to show when config is done
- add hooks for registering, loading, unregistering, and error handling for dashboard
- add grafana dashboard unit tests
