docker.userguide: Add chapter about cleanup influxdb/grafana

Added chapter about cleaning influxdb and grafana configurations.
Config files for both are stored in folders that are shared
between container and Host machine - it is good to remove them
when removing barometer docker containers in case of re-installation
or changing active setup.

+When user wants to remove current grafana and influxdb configuration,
+folowing actions have to be performed
+
+1. Stop and remove running influxdb and grafana containers
+
+.. code:: bash
+
+   sudo docker rm -f bar-grafana bar-influxdb
+
+2. Remove shared influxdb and grafana folders from the Host
+
+.. code:: bash
+
+   sudo rm -rf /var/lib/grafana
+   sudo rm -rf /var/lib/influxdb
+
+.. note::
+   Shared folders are storing configuration of grafana and influxdb
+   containers. In case of changing influxdb or grafana configuration
+   (e.g. moving influxdb to another host) it is good to perform cleanup
+   on shared folders to not affect new setup with an old configuration.
