Metricbeat metric sets modules uses wrong log level

This issue is related to: #27798

If you have a misconfiguration and set the hosts: ["http://localhost:9200"] to use a trailing / e.g. hosts: ["http://localhost:9200/"] metricbeat will write the following issue:

2021-09-08T09:19:46.039+0200    INFO    module/wrapper.go:259   Error fetching data for metricset elasticsearch.shard: HTTP error 400 in : 400 Bad Request

Those messages should be ERROR and not INFO.
