The change updates the imports to use simplejson library and fixes three unit tests. In particular TestUtils.test_parse_alarm_state_hist_message has been slightly changed to make testing more robust. Also, Python 2 specific implemetation has been removed from influxdb.line_utils . Additionally, standard library unittest.mock is used instead of the third party mock lib.
