Epic: PoE module follow ups

[alpe]

Incomplete

* Genesis elements to customize the PoE contract instantiation config (fix in code)
* Queries (CLI/GRPC) that bridge to the PoE contracts

Missing

• Export genesis via state dump
• Start chain from genesis state dump (+ validation)
  * Historical staking data for IBC see https://github.com/cosmos/cosmos-sdk/blob/v0.42.5/x/ibc/core/02-client/types/expected_keepers.go#L11
  * StakingAdapter implementation
  * Add/ remove stake ? What other commands/ queries do we need
  ~~* Where do we store Validator meta data (moniker, ...) / ~~
  * Edit validator meta data message/ command

Puzzle

• How do we edit/set the Engagement group in genesis?
  * Do we need an admin for the mixer contract?

Is this done?

We don't have support for the hard fork scenario via

• Export genesis via state dump
• Start chain from genesis state dump (+ validation)

This #49 and #50 are all about dump-state-and-restart scenario.

This would be good to have before mainnet, although I would prefer x/upgrade generally (and we could x/upgrade to a new version that supports this if needed).

Could you make one issue that explains all requirements for dump-state-and-restart and close all these (and link them to the new issue). These are old, and a bit lost in the pile.

Closing this in favour of #49 + #50 for the remaining open tasks
