This commit renames the personalSign to Sign in nim and status-go to enable `eth_signTypedData_v4` signing.
The sing request coming from the status-go API contains the signing method to be used by the client. Currently we're supporting personal sign and signTypedData_v4.
The only difference between these two signing methods is the order of challenge and address in the `params` array. This is handled in the SappsConnectorSDK::buildSignRequest
This PR is refactoring the dapps service to avoid code duplication between SDKs and also to avoid overlapping requests/responses.
It brings Browser Connect inline with Wallet Connect in terms of session management and sign transactions.
New architecture:
WalletConnectService becomes DAppsService. Its responsibility is to provide dapp access to the app. This is the component currently used by the UI
What does it do:
1. Provide dapp APIs line connect, disconnect, session requests etc
2. Spawn app notifications on dapp events
3. Timeout requests if the dapp does not respons
DAppsRequestHandler becomes DAppsModule. This component is consumed by the DAppService. Its responsibility is to aggregate all the building blocks for the dapps, but does not control any of the dapp features or consume the SDKs requests.
What does it do:
1. Aggregate all the building blocks for dapps (currently known as plugins)
DAppConnectionsPlugin - This component provides the session management features line connect, disconnect and provide a model with the connected dapps.
SignRequestPlugin - This component provides the sign request management. It receives the sign request from the dapp, translates it to what Status understands and manages the lifecycle of the request.
New component introduced (DAppsModel) to provide a common model for WC and BC. The WCDappsProvider and BCDappsProvider components are responsible to fill the model from different sources
