[system test] offline upgrade from 2.0.0 to 2.0.1 using hostname failed to copy back ip_start file

Offline upgrade from 2.0.0 to 2.0.1 using hostname failed to copy back ip_start file

Before upgrade, add hostname to ip and ip_start file

[root@cen-2501 ~]# more /opt/couchbase/var/lib/couchbase/ip
cen-2501.hq.couchbase.com
[root@cen-2501 ~]# more /opt/couchbase/var/lib/couchbase/ip_start
cen-2501.hq.couchbase.com

Then after offline upgrade, instead of copying ip file to ip_start file, upgrade process create an empty ip_start file

[root@cen-2501 ~]# rpm -U couchbase-server-enterprise_x86_64_2.0.1-154-rel.rpm
