Make rules valid within a time range

[etj]

We want some rules to be valid

• after a given date
• before a given date
• both of the previous

Use cases examples:

• allow the access to a single layer only after a given date
• deny access to a group/user after an expiration date

Implementation:

• add a datetime field valid_after; if not null, this rule will be evaluated only after the stored date

• add a datetime field valid_before; if not null, this rule will be evaluated only before the stored date

• add the date filtering in RuleFilter

• parse date filter and create criteria accordingly

• filtering in Services and REST methods

The filtering date will be provided by the requesting client.
