Missing final flag from transition-dapp CLI and all logic partaining to non-final RollApp state submissions

[kmlbgn]

Description

Currently, the transition-dapp CLI does not provide a flag for indicating whether a submission is final. This absence means that the entire logic surrounding non-final submissions, including the ability to make multiple submissions during a session and the discarding of approvals from Verifiers with each new submission, is not implemented.

Expected Behavior

The transition-dapp CLI should include a final flag to indicate whether a submission by the leader is final for a session. This would enable the proper handling of non-final submissions, such as allowing multiple submissions during a session. For each submission, all gathered approvals from Verifiers are discarded. However, Verifiers performance counter should be kept to ensure correct distribution of rewards.
