Description of problem:
=============

Mounting export with vers=3 is failing with RHCS 8.0 build.
Changes which were made in RHCS 7.1 wrt vers 3 in ganesha.conf and export file is missing in RHCS 8.0 build.

RHCS 8.0

# ceph --version
ceph version 19.1.0-3.el9cp (2032ce88d0c0820de58f7fde69952e9e1c790f42) squid (rc)


How reproducible:
=================
Always


Steps to Reproduce:
===================
1. Create ganesha cluster
2. Create a cephfs filesystem. Create an export out of filesystem
3. Mount the export on client with vers=3

Actual results:
=============
Mount on client failed with vers=3


Expected results:
============
Mount with vers=3 is supported and it should be allowed by adding the entries in ganesha.conf and export file by default in code base
