ContainerBuilder : Adds public Constructor to create ContainerBuilder instance.

[kr-santosh]

Description

This PR exposes a public ContainerBuilder constructor which would allow in this case Encryption Package to return a EncryptionContainer object.

    /// <summary>
    /// Creates an instance of ContainerBuilder .
    /// </summary>
    /// <param name="database"> The Microsoft.Azure.Cosmos.Database object.</param>
    /// <param name="name"> Azure Cosmos container name to create. </param>
    /// <param name="partitionKeyPath"> The path to the partition key. Example: /partitionKey </param>
    public ContainerBuilder(
        Database database,
        string name,
        string partitionKeyPath)

This would allow calls to DefineContainer to return an EncryptionContainer object.

public override ContainerBuilder DefineContainer(string name, string partitionKeyPath)
{
}
will return a ContainerBuilder , by passing EncryptionDatabase to ContainerBuilder which would allow us to return EncryptionContainer when calls come over to CreateContainerAsync() overriden in EncryptionDatabase to return EncryptionContainer object.
