Add ApplicationName to roles #2515
Description
Assume that a single database is shared between multiple applications. In such a case, every application may want to see & manage its own roles.
An application can set a global option (like AbpIdentityOptions.ApplicationName) and the Identity module filters data based on it and ensures that only this application related roles are managed.
If it is not set by the applcation, all roles are managed.
Maybe this is not a unique problem to Roles. We should think about it while implementing.
