* changed log level from error to trace

* incomplete during submit != synced

* parse all deploy contract arguments

* Rename Ethereum PoA primitives crate

The "sp" prefix comes from Substrate primitives, since this crate originated
in that repo. However, it is not part of Substrate anymore and its name should
be updated to reflect that.

* Sketch out how to support different bridge pallet instances

* Create a common interface for using pallet instances

* Start introducing generic instance parameter

Attemps to make the compiler happy, but I'm having second thoughts about
this approach. Commiting now as a way to have a checkpoint, but I think
I'm going to need to re-consider my approach here.

Ideally I want a change which introduces minimal changes, but this seems
to be propagating around the codebase in ways I don't want.

* Use trait objects instead of generics

* Implement traits for Boxed trait objects

This is done in order to statisfy trait bounds by types
which use these new trait objects

* Remove Clone usage for sync parameters

* Remove implementation of Default for sync params

* Require that BridgeInstance implements Debug

* Ensure that BridgeInstance trait implements Send/Sync

* Add documentation related to instances

* Rust Fmt

* Remove needless format

* Make instance CLI option case insensitive

* Replace `with_*` constructors with `new`

* Clean up usage of instance structs

* Enforce a default instance in the CLI params

* Build sync params as we process input from CLI

* Remove case insensitivity from sub-tx-mode

I think this should happen, but maybe as part of a different PR

* Process default Eth contract deployment config in CLI

* Build EthereumExchangeParams in CLI

* Process EthereumExchangeSubmitParams params in CLI

* Bump Substrate to rc5

* Bump async-std to v1.6.2

There was a bug in v.1.6.0 which kept us locked to v1.5 releases.
I think that's fixed now so I'm bumping this.

* Update bridge node runtime

* Update node service

* Update CLI

* Add SystemWeightInfo type to test runtimes

* Add RPC extension builder to service

* Directly return rpc_extensions_builder

* Allow complex types in service

This comes from Substrate, so I'd rather just keep the code as is

* Update benchmarking code for new CLI

* gas_used should be cumulative_gas_used!!!

* more runtime traces

* improve logs

* fixed PoA contract deploy (granda_authorities call)

* pause if all submitted headers were rejected

* give funds to Bertha and Carlos

* max 1 active PoA transaction in headers sync :(

* display initial header id when deploying PoA contract

* cargo fmt + clipy

* fix compilation

* clippy

* fix everything

* Add Instance type parameter to pallet

* Sketch out what the runtime could look like

* Allow runtime to compile with multiple bridge pallets

* Cargo Fmt

* Allow an instance of a PoA chain to be used with currency-exchange

I specify that it's only _an instance_ instead of _instances_ since the currency-exchange
pallet does not support multiple instances itself. What this commit does is make it so
that the different instances of the PoA chains we currently have are compatible with the
currency-exchange pallet through the implementation of the PeerBlockchain trait.

* Add Instance type parameter to Currency Exchange pallet

* Wire up currency exchange intances in runtime

* Rust Fmt

* Show sccache

* Allow Eth pallet to use a default instance

* Use a default instance in Eth pallet tests

* Remove Rialto and Kovan feature flags

Through some discussions it has been decided that the `bridge-node` should, like
Substrate's `node-template`, be a showcase of the different pallets available in
a project. Because of this I've removed the feature flags for the Rialto and Kovan
networks in favour of having both of them included in the runtime.

* Update the chain_spec to use both Rialto and Kovan configs

* Update pallet level calls used by Substrate client

Allows the project to compile. However, it should be noted that in reality
we shouldn't be hardcoding the pallet we're calling.

* Allow currency-exchange pallet to use a default instance

* Support benchmarking an instance of the Eth pallet

* Update currency exchange benchmarks to work with instances

* Fix test helpers which now need a PoA instance

* Remove Actions for checking Rialto and Kovan features

* Add missing comments

* Update Runtime API string constants

* Add issue number for generic chain support in relay

* Add Runtime APIs for instances of the currency-exchange pallet

* Rust Fmt
