[plugins] Monitoring group parameter is absent in metadata.yaml file

[Irina Povolotskaya]

The groups field is used to specify group which your plugin belongs to.
Depending on the value of the field, the plugin will fall into a specific category of the Fuel Plugins Catalog.
Currently, the following values are introduced for 'groups':
1) network
2) storage
3) storage::cinder
4) storage::glance
5) hypervisor.

If your plugin does not belong to any of these options, it will fall into Others group.
That harms a lot to a number of Monitoring plugins like LMA Collector, Zabbix, ElasticSearch-Kibana, InfluxDb-Grafana delivered in 6.1 release.

Let's provide monitoring option for those plugins.

I've also updated the wiki page https://wiki.openstack.org/wiki/Fuel/Plugins#Brand_new_features

Steps were used for verify:
1) Install master node
2) Install Fuel Plugin Builder at the nailgun container on the master node
3) Create new plugin with "group" == "monitoring"
4) Build and install plugin
5) Perform request to the nailgun API: http://<master_ip>/api/plugins. Check plugin "group" field from response.

There is a new group "monitoring".

Verified on the #521 ISO.
