Context-based restrictions module

This module can be used to provision and configure Context Based Restrictions.

See in particular the fscloud module that enables creating an opiniated account-level coarse-grained set of CBR rules and zones aligned with the "secure by default" principles.

ℹ️ Tip: Changes to context-based restriction rules are propagated worldwide and have a TTL value of 10 minutes. Rule changes might not take effect until the propagation process is complete and the TTL cache is updated.
