[Protocol Versioning] functionality for updating execution-related parameters in the Protocol State

[AlexHentschel]

Once the previous issue #7000 is done, we can store the Execution Stack Version (and other protocol parameters controlling the execution) in the Dynamic protocol state. Now we need to add functionality for updating these parameters in the Protocol State:

• implement Service Events on the protocol layer only (flow-go) for requesting to schedule a value update
• Janez to define the rules by which request for scheduling an update should be accepted or rejected
• in the Protocol State, implement this logic for accepting or rejecting request for scheduling an update as a KeyValueStoreStateMachine and add this to the Protocol State's EvolveState method
