/**
* Constructs a create command.
*
* Supported options:
*
* * autoIndexId (boolean): Specify false to disable the automatic creation
* of an index on the _id field. For replica sets, this option cannot be
* false. The default is true.
*
* This option has been deprecated since MongoDB 3.2. As of MongoDB 4.0,
* this option cannot be false when creating a replicated collection
* (i.e. a collection outside of the local database in any mongod mode).
*
* * capped (boolean): Specify true to create a capped collection. If set,
* the size option must also be specified. The default is false.
*
* * collation (document): Collation specification.
*
* This is not supported for server versions < 3.4 and will result in an
* exception at execution time if used.
*
* * flags (integer): Options for the MMAPv1 storage engine only. Must be a
* bitwise combination CreateCollection::USE_POWER_OF_2_SIZES and
* CreateCollection::NO_PADDING. The default is
* CreateCollection::USE_POWER_OF_2_SIZES.
*
* * indexOptionDefaults (document): Default configuration for indexes when
* creating the collection.
*
* * max (integer): The maximum number of documents allowed in the capped
* collection. The size option takes precedence over this limit.
*
* * maxTimeMS (integer): The maximum amount of time to allow the query to
* run.
*
* * session (MongoDB\Driver\Session): Client session.
*
* Sessions are not supported for server versions < 3.6.
*
* * size (integer): The maximum number of bytes for a capped collection.
*
* * storageEngine (document): Storage engine options.
*
* * typeMap (array): Type map for BSON deserialization. This will only be
* used for the returned command result document.
*
* * validationAction (string): Validation action.
*
* * validationLevel (string): Validation level.
*
* * validator (document): Validation rules or expressions.
*
* * writeConcern (MongoDB\Driver\WriteConcern): Write concern.
*
* This is not supported for server versions < 3.4 and will result in an
* exception at execution time if used.
*
* @see http://source.wiredtiger.com/2.4.1/struct_w_t___s_e_s_s_i_o_n.html#a358ca4141d59c345f401c58501276bbb
