* 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.

* Fix vars substition on update.

* Update comment.

* 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

* replace debug printlns with traces

* cargo fmt --all

* fixed traces

* update RUST_LOG in docker-compose

* only print hex data if error has occured

* 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
