Agent: Add a boolean to the index to indicate agent mode. (#9649)

Browse Source 
I would like to avoid extra API call's to determine if we are running in
Agent Mode, so I think we could use this approach.

This is a bootstrap of #9612

The GLOBAL_CONSOLES_LINK placeholder magic value is replaced during serving by Prometheus
and set to the consoles link if it exists. It will render a "Consoles" link in the navbar when
it is non-empty.
Placeholders replaced by Prometheus during serving:
- GLOBAL_CONSOLES_LINK is replaced and set to the consoles link if it exists.
It will render a "Consoles" link in the navbar when it is non-empty.
- PROMETHEUS_AGENT_MODE is replaced by a boolean indicating if Prometheus is running in agent mode.
It true, it will disable querying capacities in the UI and generally adapt the UI to the agent mode.
