Better out-of-the-box support for Dynatrace

[grabnerandi]

The keptn on k3s should improve the support for Dynatrace installation with the following capabilities (can be turned on/off through install flags)
#1: Automatically create a demo quality gate project that uses the default dynatrace SLO dashboard to easily demo and explore quality gates
#2: Automatically create a demo performance as a self-service project with a pre-configured jmeter test against a sample app
#3: Automatically create a demo delivery project using the simplenode sample app for multi-stage delivery
#4: Automatically create a demo remediation project that allows a user to react on Dynatrace problems
