Title: Added index settings analysis builders

Added analyzer builders only. Tokenizer, token filter and char filter builders are not added.

Usage example:

```c#
var indexSettings = new IndexSettingsBuilder()
.Analysis(analysis => analysis
.Analyzer(analyzer => analyzer
.Custom("keyword_lowercase", custom => custom
.Tokenizer(DefaultTokenizers.keyword)
.Filter(DefaultTokenFilters.lowercase))))
.Build();

connection.Put(Commands.Index("new_index"), indexSettings);
```
