Security API

[baseic]

The OmniaApi.WorkWith(Ctx.Omnia()).Security(Ctx) seems to need some TLC.

E.g. IEnumerable<string> OmniaApi.WorkWith(Ctx.Omnia()).Security(Ctx) .GetCurrentUserADGroups(string[] groups);

It is not clear that groups can be an empty array, or that this only returns AD groups used in OMF.

Also, there is a need to define the difference between PermissionRoleDefinition and PermissionRole, and how to get from one to another
