* Add import support
* Add import tests
* Fix tags/thresholds
* The type of the object is a float but the tests were using integers, so the
tests were also adjusted to match.
* Fix Float formatting
* Provide thresholds as map[string]string to deal with formatting issues
* Adjust tests to deal with loss of trailing zeros on floats
* provider/datadog Update go-datadog-api.
* provider/datadog Add support for "require_full_window" and "locked".
* provider/datadog Update tests, update doco, gofmt.
* provider/datadog Add options to update resource.
* provider/datadog "require_full_window" defaults to True, "locked" to False. Use
those initial values as the starting configuration.
* provider/datadog Update notify_audit tests to use the default value for
testAccCheckDatadogMonitorConfig and a custom value for
testAccCheckDatadogMonitorConfigUpdated.
This catches a situation where the code ignores setting the option on creation,
and the update function merely asserts the default value, versus actually changing
the value.
