Setup Spring Petclinic Rest with Elastic APM Agent

###
# I am not a Maven Guru so I am sure there is a better way to do the copy in the pom.xml
# But I am demonstrating that java apm agent is not required at compile time
# the java apm agent should probably be installed / pulled from a local or maven repo
# In PCF the entire app and app agent need to be deployed
# There are some subtleties with PCF that I will not go into here

# Prequisite setup APM running localhost
