Rate-limiter

[pavel-shkradziuk1]

Partially implemented universal library for request limiting. Library can be used as separated component. Fully implemented a rule that tested in end-to-end test. Introduced extension point that after some rework can be used to extend library by new rules(RuleTemplateDetector, IRuleTemplate). Implementation of IRuleTemplate and classes defined by methods allow to add new rule templates without changing library code. Depts:

• implementation other rules
• checking multiple rules applying
• implementation of rule template detector
• set generic violation where possible etc.
