Add new privilege raw_events

[alpe]

Background:
With bonding/unboding we have events emitted by the contract and the PoE module's msg_server. There is an amount of duplicate data with this approach. The contract's events are prefixed with wasm- so that they can not replace the ones defined in staking module.

Requires: CosmWasm/wasmd#614

Follow up tasks would be:

• provide new impl with custom event mapping (rule: reject message type events)
• add sdk type events to stake contract
• remove duplicate events from PoE module

I like the wasmd one.
Sounds like super arcane, boring technical refactoring.

This would be a nice addition to a future staking contract. And really make privileged contracts first class citizens.

I don't see this as urgent. We don't do proper faking of all the staking contracts anyway (use different proto types for messages, etc). We can look at this in the future, for now block explorers seem to work without this

This was a very old idea to be able to fully migrate go modules to contracts. Do you think this is still relevant @daniellarita ?

[daniellarita]

@ethanfrey what do you think, is this ticket still relevant?

[ethanfrey]

I think the idea is good and it would give better compatibility, but event compatibility didn't seem to be a major issue with tooling.

I would leave this in the "nice ideas" pile, where we could do if there is time for refactoring and polish, but not urgent at all
