* Separate pending and effective validator updates. - Pending validator updates do not prevent elections from concluding. - ValidatorElection overrides has_conclude to not conclude when there is a pending update for the matching height. - Effective validator updates deem past elections inconclusive. * Problem: Looking for election block is inefficient. Solution: Record placed elections, update the records upon election conclusion. * Clarify the conclusion order in Election.process_blocks. * Insert election records in bulk. Otherwise, one can significantly slow nodes down by posting a whole bunch of unique elections. * Change get_election to use find_one. * Calculate total votes without making extra query. * Fix the pending valset check. * Fix election test setup.
