[FLINK-4491] Handle index.number_of_shards in the ES connector
Implemented the Index Template and Index Mapping creation.
Number of shards and many other properties can be defined in the Index
Template.
### Usage
Before calling ElasticasearchSink instantiate ElasticSearchHelper
```java
ElasticSearchHelper esHelper = new ElasticSearchHelper(config, transports);
//Create an Index Template given a name and the json structure
esHelper.initTemplate(templateName, templateRequest);
//Create an Index Mapping given the Index Name, DocType and the json
structure
esHelper.initIndexMapping(indexName, docType, mappingsRequest);
```
### TemplateRequest example
```json
{
"template": "te*",
"settings": {
"number_of_shards": 1
},
"mappings": {
"type1": {
"_source": {
"enabled": false
},
"properties": {
"host_name": {
"type": "keyword"
},
"created_at": {
"type": "date",
"format": "EEE MMM dd HH:mm:ss Z "
}
}
}
}
}
```
### MappingRequest example
```json
{
"mappings": {
"user": {
"_all": {
"enabled": false
},
"properties": {
"title": {
"type": "string"
},
"name": {
"type": "string"
},
"age": {
"type": "integer"
}
}
}
}
}
```
