docs: Sets the value of a configuration variable in the "application" scope.
  <p> Setting the value of a configuration variable is performed as if
  each scope had its own namespace, that is, the same configuration
  variable name in one scope does not replace one stored in a different
  scope.
  
  @param context Servlet context in which the configuration variable is to
  be set
  @param name    Configuration variable name
  @param value   Configuration variable value
