config file is not compatible with InfluxDB 1.5.2 (https-private-key)

[tivvit]

Ansible Version: 2.5.5 InfluxDB Version: InfluxDB v1.5.2 (git: 1.5 02d7d4f043b34ecb4e9b2dbec298c6f9450c2a32)

Issue

private key is not configured

Steps to reproduce

run on Ubuntu

Expected behavior

configure the private key

I know that the installed InfluxDB version is not supported but it is installed on Ubuntu via the role. Maybe the version of Influx should be also set by the role?

I (hot)fixed it like this:

-  https_private_key = "{{ influxdb_http_https_private_key }}"
+  https-private-key = "{{ influxdb_http_https_private_key }}"

but the problem will be probably deeper and I did not study it.
