[Feat]: Flood protection alert nonfiction should give more context

[hugovalente-pm]

Problem

When Netdata Cloud triggers a Flood Protection notification it isn't possible to have an idea what could be main cause of it

Description

If some more context was added, similar to what is on the Home tab, users could understand if:

• one machine is having some network issue or CPU consumption spikes that could be flip-flopping the alerts, or
• major incident is happening and multiple machines are affected

Importance

really want

Value proposition

1. Users would immediately be able to assess the importance of what's happening

Proposed implementation

Add some stats like the Home tab for:

• Nodes with most alerts in the last X hours/minutes
• Top alerts in the last X hours/minutes
