[PATCH v2 3/3] ethdev: add extended meter action to Flow API

[Alexander Kozyrev <akozyrev@nvidia.com>]

Configure a meter profile at the time of the flow rule insertion.
Pass all the needed parameters to configure the meter profile
and insert the metering rule simultaneously.

The meter profile can be reused in multiple flow rules in order
to share the profile and optimize the flow insertion process.
Setting meter profile to NULL means keeping old profile config.
