feat: extend consumer chains query (#2172)

* feat: first iteration on Permissionless ICS (#2117)

* (partially) renamed chain ids to consumer ids

* renamed proposal messages

* removed global slash entry

* fixed unit tests

* added new messages

* introduced new state

* added functionality for the register and initialize messages

* renamed (partially) chainIds to consumerIds

* set consumerId to chainId association during registration

* added extra check in the initialization so unknokwn, launched, or stopped chains cannot re-initialize

* added initial work on traversing initialized chains that are to-be-launched

* fixed rebase issues after bringing the VSCMaturedPackets work in

* made it so we traverse initialization records instead of addition proposals (+ additional changes so the unit tests pass)

* renamed more chainIDs to consumerIds

* removed ClientIdToChainId state because chainId already resides on the registration record

* nit fixes in go docs

* removed MsgConsumerAddition

* added CLI commands for new messages

* removed consumer modification proposal

* removed (partially) consumer removal proposal

* rebased to pick up the inactive-validators work (PR #2079)

* introduced consumerId in the equivocation messages (and a useful query for Hermes to get the consumerId)

* added safeguard so that a validator cannot opt-in to two different chains with the same chain id

* renamed some chainIDs to consumerIds

* updated based on comments

Co-authored-by: bernd-m <43466467+bermuell@users.noreply.github.com>

* fixed integration tests

* rebased to pick up the removal of legacy proposals (#2130) and re-introduced old messages so that existing proposals can deserialize

* changes messages to only have MsgCreateConsumer and MsgUpdateConsumer and modified protos so that we are backward-compatible

* cleaned up slightly a few things (mostly committing & pushing) so people can pick up the latest changes

* fixed the CreateConsumer and UpdateConsumer logic and made most of the fields optional

* fixed hooks and the code around proposalId to consumerId

* feat: extend consumer validator query to return commission rate (backport #2162) (#2165)

* adapt #2162 changes for permissionless ICS

* nits

Co-authored-by: kirdatatjana <116630536+kirdatatjana@users.noreply.github.com>

* renamed some chainIds to consumerIds

* took into account comments and also added safeguard to reject new proposals that still use deprecated messages (e.g., MsgConsumerAddition, etc.)

* Update x/ccv/provider/types/msg.go

Co-authored-by: bernd-m <43466467+bermuell@users.noreply.github.com>

* removed double-gas charge on MsgCreateConsumer and imroved the logic of MsgUpdateConsumer

* added PopulateMinimumPowerInTopN tested

* took into account comments (using protos for marshalling string slice, fixed issues in the UpdateConsumer logic, added extra check to abort spurious proposals)

* feat: add fields to consumer validators query (#2167)

* extend consumer validators query

* nit

* nits

* fix msg order

* deprecate power for consumer_power

* modified the way we verify the new owner address, as well as nit refactoring on the ConsumerIds

* fixed some rebase issues and changed a proto to be backward-compatible
