Democracy modules

This section is relevant for chains transitioning from a standalone chain and new consumer chains that require some functionality from the x/staking module.

The democracy modules comprise x/staking, x/distribution and x/governance modules with overrides and extensions required for normal operation when participating in interchain security.

The modules are plug-and-play and only require small wiring changes to enable them.

For a full integration check the consumer-democracy example app.
