This address will be used by ovs-p4rt client for communication with P4Runtime gRPC server.

Example:
If infrap4d server is started on address 5.5.5.5 using `$P4CP_INSTALL/sbin/infrap4d --nodetach --local_stratum_url="5.5.5.5:9559" --external_stratum_urls="5.5.5.5:9339,5.5.5.5:9559"`, then start ovs-vswitchd as follows:

```bash
ovs-vswitchd --pidfile --detach --mlockall \
--log-file=/tmp/logs/ovs-vswitchd.log --grpc-addr="5.5.5.5"
