Kapacitor state module.
:configuration: This module accepts connection configuration details either as
parameters or as configuration settings in /etc/salt/minion on the relevant
minions::
kapacitor.unsafe_ssl: 'false'
kapacitor.protocol: 'http'
kapacitor.host: 'localhost'
kapacitor.port: 9092
This data can also be passed into pillar. Options passed into opts will
overwrite options passed into pillar.

'''
Ensure that a task is present and up-to-date in Kapacitor.
name
Name of the task.
tick_script
Path to the TICK script for the task. Can be a salt:// source.
task_type
Task type. Defaults to 'stream'
dbrps
A list of databases and retention policies in "dbname"."rpname" format
to fetch data from. For backward compatibility, the value of
'database' and 'retention_policy' will be merged as part of dbrps.
.. versionadded:: 2019.2.0
database
Which database to fetch data from. Defaults to None, which will use the
default database in InfluxDB.
retention_policy
Which retention policy to fetch data from. Defaults to 'default'.
enable
Whether to enable the task or not. Defaults to True.
