vrrp: add stats support and update API
Add simple counter statistics to VRRP, based on a subset of those defined in RFC8347. Add an update API that allows in-place modification of an existing instance. The method returns a vrrp_index which can be used both for retrieving statistics and to modify non-key parameters. Also add a delete method which will take that vrrp_index as parameter. Type: improvement Signed-off-by: Emanuele Di Pascale <lele84@gmail.com> Change-Id: I2cd11467b4dbd9dfdb5aa748783144b4883dba57
