Gatling Gerrit: Generate unique target URL

When deploying gerrit in AWS, a new DNS 'A' entry is created with a
domain name such as "jenkins-master-demo.gerrit-demo.gerritforgeaws.com"

During subsequent runs of the gerrit-gatling job however, this DNS cache
resolution might still be cached, effectively preventing jenkins to
resolve the new URL.

Create unique target URLs, such as
"jenkins-<timestamp>.gerrit-demo.gerritforgeaws.com" so that each run is
independent from any previous execution.

Bug: Issue 14192
