Multinode configuration through UI

[ShahanaFarooqui]

Currently, user has to manually create and configure JSON file for node settings. It will be easier and error proof, if user can configure/update nodes through UI.

Two scenarios need to be handled here:

1. First time user
2. Existing user

First time user - As soon as the RTL page is accessed, without any config file. RTL will take the user to the config page to allow user to add config parameters. Once the parameters are saved, the user is taken to the home page.

Existing user - Existing user should be able to add config params for new nodes to be configured or make changes to current config params

Missing values in API are:
channelBackupPath, bitcoindConfigPath, enableLogging, lnServerUrl, swapServerUrl, macaroonConfigPath, lnImplementation, lnNode, lndConfigPath.
