#4688 use userPW instead of password in xcatws-test.sh

[BaiYuan]

We use userPW instead of password in xcatws.cgi, but do not update this in xcatws-test.sh;
When running xcatws-test.sh, there is error:
reproduce:
[root@c910f04x41 ws]# ./xcatws-test.sh -u root -p cluster

---

** Username: root
** Password: cluster
** Hostname: 127.0.0.1

Run: [Get all available resource]
curl -X GET -k https://127.0.0.1/xcatws/?pretty=1&userName=root&password=cluster
Output:

Run: [Get all global configuration resource]
curl -X GET -k https://127.0.0.1/xcatws/globalconf?pretty=1&userName=root&password=cluster
Output:

FAILED to continue. See the error message in 'error' section.
