What was done?

Our composite commands such as "quorum list" have been refactored to make them truly compatible with other features, such as whitelist, see https://github.com/dashpay/dash/pull/6052 https://github.com/dashpay/dash/pull/6051 https://github.com/dashpay/dash/pull/6055 and other related PRs

This PR makes whitelist feature to be compatible with composite commands.

Instead implementing additional users such "dapi" better to provide universal way which do not require new build for every new API that has been used by platform, let's simplify things.

Platform at their side can use config such as this one (created based on shumkov's example):

rpc: {
          host: '127.0.0.1',
          port: 9998,
          users: [
            {
              user: 'dashmate',
              password: 'rpcpassword',
              whitelist: null,
              lowPriority: false,
            },
            {
              username: 'platform-dapi',
              password: 'rpcpassword',
              whitelist: [],
              lowPriority: true,
            },
            {
              username: 'platform-drive-consensus',
              password: 'rpcpassword',
              whitelist: [getbestchainlock,getblockchaininfo,getrawtransaction,submitchainlock,verifychainlock,protx_listdiff,quorum_listextended,quorum_info,getassetunlockstatuses,sendrawtransaction,mnsync_status]
              lowPriority: false,
            },
            {
              username: 'platform-drive-other',
              password: 'rpcpassword',
              whitelist: [getbestchainlock,getblockchaininfo,getrawtransaction,submitchainlock,verifychainlock,protx_listdiff,quorum_listextended,quorum_info,getassetunlockstatuses,sendrawtransaction,mnsync_status]
],
              lowPriority: true,
            },
          ],
          allowIps: ['127.0.0.1', '172.16.0.0/12', '192.168.0.0/16'],
        },

We should split this PR in 2 separate ones imo:

• support for composite commands in -rpcwhitelist
• introducing quorum platformsign
