This PR is dirty hack workaround for #294 issue. It starts LES service with sync disabled (by MaxPeers option set to 0), even if Upstream is enabled. This ensures that all RPC calls are registered in local node (they are registered during LES service initialization and do not exist if LES service is not activated).
- API is async
- Node manager, backend and API modules have more that 90% coverage
- For each level (node manager, backend, public API) random testing
was used to ensure that we don't have race conditions
- node: signals and node reset, fixes#152
- tests update (testify is used)
- node manager refactored, race conditions fixed
- node wrapper has been removed, we rely on go-ethereum node now
- tx queue refactored
- jail refactored
- backend and API introduced
