Make log message topics more consistent

[mountaindude]

Over the years more and more refined log messages have been used in Butler.

For example, log entries related to the recent addition of writing successful reload data to InfluxDb are prefixed with RELOAD TASK SUCCESS INFLUXDB.

This is better than the older webhook notification feature, where log messages are prefixed with WEBHOOKOUTFAILED.

Review log entry prefixes and make them more consistent across the entire Butler code base.
As a general rule of thumb, place the destination system first, for example INFLUXDB RELOAD TASK SUCCESS rather than RELOAD TASK SUCCESS INFLUXDB
