Fix antrea-io#5681 Network policy didn't work when using a server Pod to establish a connection to the service provided by itself. This hairpin service connection initiated through a local Pod will be SNATed to the gateway IP, which will prevent it from being correctly categorized by the network policy during the Ingress rule enforcement. This commit added a bypass flow to always allow the hairpin service connection to address this issue. Given we don't consider self-access blocking to be a valid case.

When Antrea-Proxy is disabled, we can't categorize it as a hairpin service, so this test case can't pass. Opened PR #5705 fixing it. |
1. Skip allowHairpinSerivce test when Antrea-Proxy is disabled. 2. Add documentation including the behavior of the hairpin service when Antrea-Proxy is enabled and disabled. Signed-off-by: graysonwu <wgrayson@vmware.com>
