* Problem: `ValidatorElection` and `MigrationElection` need to inherit from a common `Election` class
Solution: Factored the common logic out of `ValidatorElection` and moved it to `Election` parent class
* Problem: Adding base58 as a requirement seems to break the build...
Solution: Reverting the changes
* Problem: Responding to a suggestion for improved method naming
Solution: Refactored `get_result_by_election_id` to `get_election_result_by_id`
* Problem: No need to store different types of elections in their own tables
Solution: Remove `DB_TABLE` property from `Election` class
* Revert "Problem: No need to store different types of elections in their own tables"
This reverts commit db45374d3c690429d18a25bcc319f8056c016500.
* Problem: Missed a method in `Bigchain` class when updating the naming for an election method
Solution: Finished the refactoring
* Problem: Need a table to store data for all elections
Solution: Created the `elections` table with secondary_index `election_id`
* Problem: `Election` class needs to be updated to store concluded elections in the `elections` table
Solution: Updated the class to use the new table
* Problem: `UpsertValidatorVote` can be generalized to just be `Vote`
Solution: Renamed, refactored and moved the `Vote` class to tie in with the more general `Election` base class
* Problem: Error in docstring return signature
Solution: Fixed the docstring
* Problem: Hardcoded reference to the `VOTE_TYPE` in `Election` base class
Solution: Pointed the reference to the class variable
* Problem: Schema still refers to `ValidatorElectionVote` instead of `Vote`
Solution: Renamed `TX_SCHEMA_VALIDATOR_ELECTION_VOTE` as `TX_SCHEMA_VOTE`
* Problem: `Election` class variable `ELECTION_TYPE` is overly specific
Solution: Renamed `ELECTION_TYPE` to `OPERATION`
* Problem: Command line options for `upsert-validator` can be generalized to manage any type of election
Solution: Refactored the CLI to manage generalized elections
* Problem: Default for `show_election` not implemented for `Election` class
Solution: Create a default method that work if all fields in the 'asset[data]' can be displayed without additional formatting
* Problem: Multiple small issues with style etc.
Solution: Addressed comments from PR
* Problem: `Election` class variable to `VOTE_TYPE` unnecessary
Solution: Removed the variable and hardcoded everything to use the `Vote` class
* Problem: Minor style issues with PR
Solution: Addressing comments
* Problem: Changes to format for validator keys broke some tests
Solution: Aligned the tests to reflect the changed key format
* Problem: `election show` command displaying the base56 public key
Solution: Cast any public key to base64
* Problem: `election_parser` help message still refers to upsert-validator
Solution: Updated the help message
* Problem: `ValidatorElection` and `MigrationElection` need to inherit from a common `Election` class.
Solution: Factored the common logic out of `ValidatorElection` and moved it to `Election` parent class.
* Problem: No need to store different types of elections in their own tables
Solution: Remove `DB_TABLE` property from `Election` class.
Solution: Created the `elections` table with secondary_index `election_id`.
* Problem: `UpsertValidatorVote` can be generalized to just be `Vote`
Solution: Renamed, refactored and moved the `Vote` class to tie in with the more general `Election` base class.
* Problem: `election_id` is not unique if two elections have the same properties.
Solution: Added a random `uuid4` seed to enforce uniqueness.
* Problem: we have unused and outdated fixtures
Solution: clean up fixtures and tests accordingly
* Problem: there are still unused fixtures
Solution: remove Merlin keys
* Problem: There are unnecessary markers
Solution: remove the tendermint marker for tests
* Problem: Source files contain no license info
Solution: Add comments with SPDX license info to source files
* Python 3 files don't need # -*- coding: utf-8 -*-
