JS function for advanced auth with options #6447

Description

Multiple protocols supported in javascript requires specific and custom options to negotiate connection. Most of the current implementations accept basic authentication (username:password) but lack the capability to provide specific options.
The task is about investigating a generic solution for complex authenticated protocols. One possible approach could be implementing a generic auth method like the following one:

type ExtendedConnectOptions struct {
  Username string
  Password string
  ...
}

ConnectWithOptions(options *ExtendedConnectOptions)

Then refactoring existing methods to just use this more generic one and deprecating the existing connect methods recommending to use the new one.
