Performance test hanging

When db errors occur the performance hangs without a timeout. Set a timeout to avoid that behaviour:
e.g. https://ci-jenkins-csb-narayana.apps.ocp-c1.prod.psi.redhat.com/view/Pull/job/btny-pulls-narayana-jdbcobjectstore/DB_TYPE=mysql,jdk=openJDK11,label=jnlp-agent/20/console and https://ci-jenkins-csb-narayana.apps.ocp-c1.prod.psi.redhat.com/view/Pull/job/btny-pulls-narayana-jdbcobjectstore/DB_TYPE=mysql,jdk=openJDK11,label=jnlp-agent/22/console
