Update library to allow optional VPN configurations. This in turn allows
a module to be used with a provider, where the configuration is
generated on the fly.
Mainly:
- Aggregate shared/mock entities in less scattered files
- Review package dependencies
Also:
- Decouple ProfileRepository from Core Data Repository in UtilsLibrary
(filters done by ProfileManager)
Profiles are being maintained in two places:
- Core Data
- NetworkExtension
Core Data is redundant for local profiles, so make NetworkExtension the
only source of truth.
