> This patch adapts mlx5 PMD to changes in mlx5dr API regarding action
> templates. It changes the following:
> 
> 1. Actions template creation:
> 
>     - Flow actions types are translated to mlx5dr action types in order
>       to create mlx5dr_action_template object.
>     - An offset is assigned to each flow action. This offset is used to
>       predetermine action's location in rule_acts array passed on rule
>       creation.
> 
> 2. Template table creation:
> 
>     - Fixed actions are created and put in rule_acts cache using
>       predetermined offsets
>     - mlx5dr matcher is parametrized by action templates bound to
>       template table.
>     - mlx5dr matcher is configured to optimize rule creation based on
>       passed rule indices.
> 
> 3. Flow rule creation:
> 
>     - mlx5dr rule is parametrized by action template on which these
>       rule's actions are based.
>     - Rule index hint is provided to mlx5dr.
