Adapt CloneUsingBothProtocols to perform load testing
This change introduces new numberOfUsers parameter that specifies the
amount of concurrent users to run the load test. By default the value
of numberOfUsers is one.

Scenario development is often done using locally running Gerrit systems under test, which are
sometimes dockerized.
+==== Number of users
+
+The `number_of_users` property can be used to scale scenario steps to run with the specified number
+of concurrent users. The value of this property remains `1` by default. For example, this sets the
+number of concurrent users to 10:
+
+* `-Dcom.google.gerrit.scenarios.number_of_users=10`
+
+This will make scenarios that support the `number_of_users` property to inject that many users
+concurrently for load testing.
