Include in User Guide / sample scripts how to save to Cosmos DB

See original GitHub issue

While the example to write to Cosmos DB is in CosmosDBDataFrameSpec.scala - this is not at all obvious. Should provide write example directly in and user guide.

To save a DataFrame to Cosmos DB based on the flights example used thorughout this documentation:

// Import SaveMode so you can Overwrite, Append, ErrorIfExists, Ignore
import org.apache.spark.sql.{Row, SaveMode, SparkSession}

// Create new DataFrame `df` which has slightly flights information 
// i.e. change the delay value to -999
val df = spark.sql("select -999 as delay, distance, origin, date, destination from c limit 5")

// Save to Cosmos DB (using Append in this case)
//    Ensure the baseConfig contains a Read-Write Key
//    The key provided in our examples is a Read-Only Key
