Build an optional stimulated security role layer

[Cloud-Awesome]

• Have a list of IEntityPermission to include the different permissions injected into ISimulatorOptions
• To level boolean on whether to ignore missing entities (so that users can just test the but they want without having to set up complex data)
• Create a generic static PrivilegeCalculator to validate on a per record, per message basis
  • Needs to include reference to owner and business unit etc. (Access Teams will cube post-MVP!!)
• Enhance all existing Organisation Requests to enforce security on the specific message and record(s) as appropriate
