Agents by node summary

[jesuslinares]

Currently, there is a visualization for showing the alerts by node. I would like to see the same visualization but showing the agent by node.

This is a real example:

My master node failed, so all my agents were moved to the worker node. So, the alerts increased in this one. I would like to see the number of agents since it is a good way to check if all the agents were moved to another node.

This is a possible visualization:

I created a branch with the visualization in the Dashboard overview->general Issue-1539

Previously we tried to generate a visualization using the surveillance index data, but in environments with many agents, the visualization is not efficient.

When this Issue (#2064) is finished we can save the output of this request and generate a display using the "n_active_agents" field.
