Added SampleLabel parsing, which can be used to send custom fields to ElasticSearch.

[swetrify]

It uses SampleLabel which is split by delimiter (default is “_”) and then for each split value it adds key-value pairs based on second delimiter (default is “:”).
Example:

SampleLabel "Id:01_Transaction:Login" is split by delimiter “_” as

1. Id:01
2. Transaction:Login

which is then split as key-value pairs by delimiter “:”

1. key = Id, value = 01
2. key = Transaction, value = Login

and sent to ElasticSearch.

There are 3 new settings for the plugin:

1. es.parse.samplelabel – turn on and off SampleLabel parsing (default is off)

2. es.parse.samplelabel.delimiter – delimiter for splitting each parameter

3. es.parse.samplelabel.keyvalue.delimiter – delimiter for splitting key-value pairs from parameter
