Implement annotation to support matching routes by HTTP method, headers, and url paramaters

[johnlanni]

How could it be?

Examples:

1. Match by method

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  annotations:
    # support matching multiple or single method 
    higress.io/match-method: "GET POST PATCH"
  name: foo
spec:
  ingressClassName: higress  
  rules:
  - http:
      paths:
      - pathType: Exact
        path: "/"
...

2. Match by headers

format:

higress.io/<exact|regex|prefix>-match-header-<header key>: "<part or all of the header value>"

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  annotations:
    # exact matching
    higress.io/exact-match-header-abc: "123"
    # regex matching
    higress.io/regex-match-header-content-type: "application/(json|xml)"
    # prefix matching
    higress.io/prefix-match-header-user-id: "10086-1"
  name: foo
spec:
  ingressClassName: higress  
  rules:
  - http:
      paths:
      - pathType: Exact
        path: "/"
...

2. Match by url parameters

format:

higress.io/<exact|regex|prefix>-match-query-<param key>: "<part or all of the param value>"

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  annotations:
    # exact matching
    higress.io/exact-match-query-abc: "123"
    # regex matching
    higress.io/regex-match-query-name: "B.*"
    # prefix matching
    higress.io/prefix-match-query-age: "2"
  name: foo
spec:
  ingressClassName: higress  
  rules:
  - http:
      paths:
      - pathType: Exact
        path: "/"
...
