db.createRole(
   {
     role: "manageCustomDatabases",
     privileges: [
       { resource: { db: "custom*", collection: "custom.*" }, actions: [ "find", "update", "insert", "remove" ] }
     ],
     ...
   }
)

It would be great to be able to use wildcard databases when creating privileges for user roles.
both for the creation of new databases and the management of the existing.

We needs to be able to create roles that enable multitenant architecture.
For exemple, in order to create dynamicaly databases per tenant and per microservices.

We have for exemple 2 microservices: microservice1 et microservice2
and 2 tenant: tenant 1 and tenant 2.
And we want to create RoleMicroservice1 and RoleMicroservice2

db.createRole(
   {
     role: "RoleMicroservice1",
     privileges: [
       { resource: { db: "*-microservice1", collection: ".*" }, actions: [ "find", "update", "insert", "remove" ] }
     ],
     ...
   }
)

This would make it easier for administrators to manage permissions for all databases but enables our developers to create dynamicaly databases without impact on other microservices databases.
