Li Zhang 5f0d54f372 ethdev: add pre-defined meter policy API
Currently, the flow meter policy does not support multiple actions
per color; also the allowed action types per color are very limited.
In addition, the policy cannot be pre-defined.

Due to the growing in flow actions offload abilities there is a potential
for the user to use variety of actions per color differently.
This new meter policy API comes to allow this potential in the most ethdev
common way using rte_flow action definition.
A list of rte_flow actions will be provided by the user per color
in order to create a meter policy.
In addition, the API forces to pre-define the policy before
the meters creation in order to allow sharing of single policy
with multiple meters efficiently.

meter_policy_id is added into struct rte_mtr_params.
So that it can get the policy during the meters creation.

Allow coloring the packet using a new rte_flow_action_color
as could be done by the old policy API.

Add two common policy template as macros in the head file.

The next API function were added:
- rte_mtr_meter_policy_add
- rte_mtr_meter_policy_delete
- rte_mtr_meter_policy_update
- rte_mtr_meter_policy_validate
The next struct was changed:
- rte_mtr_params
- rte_mtr_capabilities
The next API was deleted:
- rte_mtr_policer_actions_update

To support this API the following app were changed:
app/test-flow-perf: clean meter policer
app/testpmd: clean meter policer

To support this API the following drivers were changed:
net/softnic: support meter policy API
1. Cleans meter rte_mtr_policer_action.
2. Supports policy API to get color action as policer action did.
   The color action will be mapped into rte_table_action_policer.

net/mlx5: clean meter creation management
Cleans and breaks part of the current meter management
in order to allow better design with policy API.
