Added

• Purge all cache (curl -X PURGE -H "name: *")
• Purge the cache belong to a proxy (curl -X PURGE -H "name: proxy-name")
• Purge the cache belong to a cache-rule (curl -X PURGE -H "name: cache-rule-name")

Changed

• Performance improvement by parsing necessary data in advance instead of doing that in iterating cache-rules
• Unified cache manager entry
