[devopsmash]

Describe the bug

ERRO[2021-09-06T07:50:40Z] Failed to post data to els. Error:elastic: Error 400 (Bad Request): Rejecting mapping update to [botkube-2021-09-06] as the final mapping would have more than 1 type: [_doc, botkube-event] [type=illegal_argument_exception] 

The ability to have multiple mapping types per index has been removed in 6.0. New indices will be restricted to a single type. This is the first step in the plan to remove mapping types altogether. Indices created in 5.x will continue to support multiple mapping types.

To Reproduce

1. use elasticsearch communication
2. create index template to botkube-* index pattern with default options
3. create kibana Index Pattern with Time field: 'TimeStamp'
4. wait couple of days until you will get the bug above
