Support eth_requestAccounts

[gpersoon]

Expected behavior

Begin able to use eth_requestAccounts in a native way.
Because metamask will deprecate ethereum.enable().
See: https://metamask.github.io/metamask-docs/API_Reference/Ethereum_Provider#new-api

Actual behavior

It possible to use eth_requestAccounts in the following way:

web3.extend({   
                methods: [{
                    name: 'eth_requestAccounts',
                    call: 'eth_requestAccounts',
                    params: 0
                }]
            }); 
await web3.eth_requestAccounts();
