docs: Acquire remote connection url from request parameter.
  If current user is not connected to application
  from url - moskito will be connected to this application.
  This made up for possibility to share links on moskito-inspect pages.
  
  This method expects, that request will contain `remoteConnection` parameter
  with value contains host and port separated by column. Example : `localhost:9401`.
  If request have no such parameter - current connection will not be changed.
  
  @param req current request object
