testpmd: shared action usage

In this section testpmd command syntax should be treated as pseudo-code,
may be out of sync with future testpmd syntax for shared action cli.
In order to utilize introduced API testpmd cli may implement following
extension
create/update/destroy/query shared action accordingly

flow shared_action {port} create [action_id {id}]
	[ingress] [egress] action {action} / end
flow shared_action {port} update {id} action {action} / end
flow shared_action {port} destroy action_id {id} [...]
flow shared_action {port} query {id}

testpmd example:

configure rss to queues 1 & 2

> flow shared_action 0 create action_id 100 \
	ingress action rss queues 1 2 end / end

create flow rule utilizing shared action

> flow create 0 ingress \
    pattern eth dst is 0c:42:a1:15:fd:ac / ipv6 / tcp / end \
  actions shared 100 / end

add 2 more queues

> flow shared_action 0 modify 100 action rss queues 1 2 3 4 end / end
