[BUG] Cannot filter minimum level only for ElasticSearch

[pantonis]

I cannot make this library work with the way Serilog.Sinks.ElasticSearch works by specifying MinimumLevel only for ElasticSearch and not for the File or Console Sinks. e.g As of now I can manage filtering for files but not for elastic search where I want only errors to be written in ElasticSearch
