Add Gateway API filter and timeout support to HTTPRoute resources

What does this MR do?

Add Gateway API filter and timeout support to HTTPRoute resources

• Add gatewayRoute.filters to all HTTPRoute resources
• Add gatewayRoute.timeouts to MinIO, Pages

Gaps

For canary deployments, the sophisticated orchestration required would need external tooling (e.g., Argo), so I'd suggest we rule it out of scope.

Test plan

Apply the example values.yaml, then check the created HTTPRoute, we should see the filters/timeout is configured.

Example values.yaml:

nginx-ingress:
  enabled: false

global:
  hosts:
    externalIP: 127.0.0.1
  minio:
    enabled: true
  pages:
    enabled: true
  gatewayApi:
    enabled: true
    installEnvoy: true

If use test with caproni, clone this branch to ./gitlab and run a helm dependency update, use this caproni with the above values:

version: 2

cluster:
  driver: k3d # or colima
  network:
    hostname: gitlab.caproni.test
    additional_hostnames:
      - registry.gitlab.caproni.test
  k3d:
    agents: 1
    servers: 1
    # We need https://gitlab.com/gitlab-org/caproni/-/merge_requests/222
    # to disable the default Traefik ingress controller, which conflicts with GitLab's bundled one. 
    extra_args:
      - --k3s-arg=--disable=traefik@server:*

repositories:
  gitlab-chart:
