Should not require any install or config changes to
use the default Influxdb.

The time field was name timestamp which caused influxdb to use the
write time for the time field. If multiple Alarm History messages
were written, Influxdb only kept the last because the times were
not unique.

whole number values (such as 0) are json decoded as type int
If the value field is first written to InfluxDB as type int (example: 0)
and later as type float (example 0.123), InfluxDB throws a
"field type conflict" exception. Forcing all data to type float fixes.

Adding six to the requirements file to handle version conflict between the
influxdb and Kazoo libraries.
Added monasca-common to requirements and removed kafka and kazoo libraries

Always store {} when value_meta is empty for Influxdb.
Needed because the Java Influxdb driver is
capable of storing an empty string, but the
Python Influxdb driver is not.

The Java Persister converts camelCase to snake_case for
the alarm state transition sub_alarms JSON element.
The python persister needs to do the same.
The following element names in the alarm state transition
sub_alarm element need to be converted to snake_case:
subAlarmExpression -> sub_alarm_expression
metricDefinition -> metric_definition
alarmState -> alarm_state
These elements originate from the Monasca Threshold Engine.
Ideally, the Threshold Engine should be modified to send
the JSON in snake_case.

change 'name' to 'measurement'.
change 'timestamp' to 'time'.
