HDDS-5234. Change default grpc and ratis ports for scm ha

[sadanand48]

What changes were proposed in this pull request?

Currently, by default scm ratis and scm grpc ports are defined to be 9865 and 9866 by default. These ports are also used for datanode https and datanode ports for hdfs by default hence may lead to port conflict issue in ozone deployment alongside hdfs . These ports are replaced with port numbers 9894 and 9895 respectively.

Tested manually on a docker scm ha cluster

This might have some impact for someone who is using from the apache/master branch.
Mostly the port for SCM Ratis and Grpc Port is changed so after the upgrade SCM Ratis and Grpc will start on new ports. Is this only the impact or there any impact other than this?

Thanks @bharatviswa504 for the notification! We are fine with this change.

We will explicitly set the ratis port and grpc port to 9865 and 9866 respectively before next upgrade, so that our running cluster will keep using the old port, thus not be affected.

Thanks @GlenGeng for the confirmation.

I am +1, as this is a progress feature, mostly it will not be used by others.

But if someone is using they can follow a similar suggestion by @GlenGeng adding the port configs with the previous value.

+1
