Update monitoring doc to include search and replace 'myproject'

https://access.redhat.com/documentation/en-us/red_hat_amq/7.7/html-single/deploying_amq_interconnect_on_openshift/index#setting-up-prometheus-grafana-router-ocp

asks users to replace 'myproject' in deploy-monitoring.sh however this is not sufficient

Proposed Solution
Introduce the script as an example and explain that they need to replace all instances of 'myproject' in the cloned repo.

eallen@redhat.com Does this sound right?
