acl-plugin: add a debug CLI to print 5-tuple structure in human readable format from hex representation
Even though the trace now prints the hex as well as human readable format for acl plugin, it can be handy to have a separate function which allows to decode the hex. So add this debug CLI. Change-Id: I1db133a043374817ea9e94ae3736b8a98630669d Signed-off-by: Andrew Yourtchenko <ayourtch@gmail.com>
