Refactor enforced/expected PCRs (#553)

Browse source 
* Merge enforced and expected measurements

* Update measurement generation to new format

* Write expected measurements hex encoded by default

* Allow hex or base64 encoded expected measurements

* Allow hex or base64 encoded clusterID

* Allow security upgrades to warnOnly flag

* Upload signed measurements in JSON format

* Fetch measurements either from JSON or YAML

* Use yaml.v3 instead of yaml.v2

* Error on invalid enforced selection

* Add placeholder measurements to config

* Update e2e test to new measurement format
