Is your feature request related to a problem? Please describe.
In a multi-tenant cluster where a secondary application tenant is using the DB Console metrics pages, only certain types of dashboards are relevant to a secondary application tenant.

For example, a SQL dashboard is relevant to a secondary application tenant, but a Hardware dashboard likely isn't (this is system-tenant information).

Describe the solution you'd like
Filter the list of dashboard options shown to secondary tenants to only include those relevant to an app tenant.
