Override conversion rate in estimate-message-fee RPC #1189

related #1138

This PR, if accepted would require changes in P<>K integration branch + our UI (cc @hbulgarini). So, probably, should be reviewed later. The general idea is that message submitter may know that actual conversion rate has been updated in real world && he'll use this updated rate when computing message fee. There are couple of caveats, though:

  1. now all our lanes are paid and are assumed to be served by rational relayers, so it mean that even if actual conversion rate is now lesser than stored, the submitter still has to pay fee, computed with larger rate. Otherwise, send-message tx will fail. So fee should be computed as max(estimate_without_fee_overrride(), estimate_with_fee_override());
  2. given (1), in regular configurations, this is only useful if conversion-rate-update mechanism (either automatic or manual) is lagging (see Conversion rate between RLT <> MLAU must be updated before starting messages generation #1138 for example). That's because relayer also looks at actual conversion rate. So in theory in scenarios where we assume all actors are honest (both senders and relayers), we may ignore on-chain conversion rate at all. But that's not the best idea.

This PR only adds an additional argument to RPC methods. If it'll be accepted, I'll change all our relayer subcommands to use real conversion rate when messages are submitted.

It's just a test, so it should be fine :)

Oh, sorry! didn't notice it's a test code.

* Add `AtLeast32BitUnsigned` for MessageLance::SourceChainBalance (#1207)

* Fix UI deployment. (#1211)

* Remove unused PoA<>Substrate bridge (#1210)

* Decouple the PoA bridge code from Rialto

* Remove PoA bridge documentation
* Remove primitives/ethereum-poa code
* Decouple Rialto from currency-exchange
* Fix building with runtime-benchmarks
* Fix should_encode_bridge_send_message_call test
    Because we removed some runtime modules/pallets, the
    substrate2substrate bridge pallet has a different index within
    the runtime so its calls have a different encoding.
    Update the test to use the new encoding.
* Update readme - no more PoA bridge
* Remove deployments/bridges/poa-rialto
    Also removes:
    - deployments/networks/eth-poa.yml
    - deployments/networks/OpenEthereum.Dockerfile
* Remove deployments/dev/poa-config
* Update deployments readme - no more PoA bridge
* Remove eth-related scripts
    Deletes:
    - deployments/networks/eth-poa.yml
    - scripts/run-openethereum-node.sh
* Remove poa-relay from gitlab-ci

* Remove unused `relays/headers` (#1216)

* Decouple `relays/client-substrate` from `headers_relay`
