Refactor enforced/expected PCRs (#553)
* 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 Signed-off-by: Daniel Weiße <dw@edgeless.systems>
