Some Route Predicates Don't Work With Regex Patterns

The cookie, header, and query route predicate factories don't match .* patterns and instead return a 404. At the very least it should return a 500, but I believe these patterns should match

spring:  
  cloud:    
    gateway:      
      routes:      
      - id: query_route        
         uri: https://example.org        
         predicates:        
         - Query=test, a.*b

spring:  
  cloud:    
    gateway:      
      routes:      
      - id: header_route        
         uri: https://example.org        
         predicates:        
         - Header=Test, a.*b

spring:  
  cloud:    
    gateway:      
      routes:      
      - id: header_route        
         uri: https://example.org        
         predicates:        
         - Cookie=test, a.*b

Start by locating the cookie, header, and query route predicate factories described in the issue, then reproduce the supplied a.*b patterns. Done means these predicates match the intended regex patterns instead of returning a 404; the fallback behavior should also be checked against the reported 500 expectation.
