Is your feature request related to a problem? Please describe the problem.

The number of metrics, diagnostics and activities has been steadily increasing; including for back compat of previous depreciated diagnostics (most handled by HostingApplicationDiagnostics); however there is no easy way to switch this off other than completely re-writing your own WebHost (as per NethermindEth/nethermind#8879)

Describe the solution you'd like

Be able to switch of the diagnostic types explicitly and short circuit these paths (e.g. might just want to switch off Activity creation)

Just curious, how much do you save by turning them off with your custom host?

Isn't vast; but have grafana and own custom metrics on top, so is additional cruft; also providing internal observability via Activities isn't always desirable (information leakage) aside from the allocations
