adding performance test files

performance_test/README.md

+# PERFORMANCE TEST
+separate test.py files for both *PRISM* sites `vhr18` and `emg`, using `*locust*` testing tool.
+
+# USAGE
+
+```bash
+# to test vhr18
+locust -f <path_to_file>/vhr18.py 
+
+# to test emg
+locust -f <path_to_file>/emg.py
+
+```
+
+### Requirements
+
+installed `locust`.
+
+### Authourization
+replace the value of `auth` in both test files with the `VS` credintials ( username, passwors).
+
+```python
+
+self.client.get(f"{item}", auth=('username', 'Password'))
+```
+
