KUDU-2612: allow aborting after beginning to commit

This patch adjusts the TxnStatusManager state machine to include a new
FINALIZE_IN_PROGRESS state to serve as an intermediate step between
COMMIT_IN_PROGRESS and COMMITTED. The goal is to allow for aborts to
occur in the event that we've begun committing, but not yet called
FINALIZE_TXN on any of the transaction's participants, which may be
desirable in cases where anything surprising has happened on the
participants (e.g. if they're deleted).
