pmdaelasticsearch.python doesn't work in secured elasticsearch cluster(using https)

[Saiprakash9]

DEFAULT_URL in pmdaelasticsearch.python works only in unsecured cluster. Please let us know if there is any way we can use this script in secured environment. So for secured environment we can have default url as below DEFAULT_URL = "https://localhost:%s/" with additional option to send username and password for authentication when accessing elasticsearch(when xpack is enabled) and also an option to ignore validation of ca certificate from server (like using -k in DEFAULT URL)
