Add dynamic list of links on cluster Overview and database Info pages

[StekPerepolnen]

It's currently not possible to define links dynamically.
In the latest version of the UI, for a cluster you can define:

"link_cores": "Coredumps",
"link_logging": "Logging",
"link_slo-logs": "SLO Logs"

For a database:

"field_monitoring-link": "Monitoring",
"field_logs-link": "Logs"

As far as I can tell, the list of parameters currently passed based on the database is sufficient. But I’d like to expand the list of links. For that, we need to define:

• a link template
• a display name for the UI
• optionally, a link icon (not critical)
