Implement MongoPool

The MongoPool class does nothing besides throwing E_DEPRECATED around, so we'll do just that.

-     *         each pool, this function shows the following fields: $in use The number of
-     *         connections currently being used by Mongo instances. $in pool The number of
-     *         connections currently in the pool (not being used). $remaining The number of
-     *         connections that could be created by this pool. For example, suppose a pool had
-     *         5 connections remaining and 3 connections in the pool. We could create 8 new
-     *         instances of Mongo before we exhausted this pool (assuming no instances of Mongo
-     *         went out of scope, returning their connections to the pool). A negative number
-     *         means that this pool will spawn unlimited connections. Before a pool is created,
-     *         you can change the max number of connections by calling Mongo::setPoolSize. Once
-     *         a pool is showing up in the output of this function, its size cannot be changed.
-     *         $total The total number of connections allowed for this pool. This should be
-     *         greater than or equal to "in use" + "in pool" (or -1). $timeout The socket
-     *         timeout for connections in this pool. This is how long connections in this pool
-     *         will attempt to connect to a server before giving up. $waiting If you have
-     *         capped the pool size, workers requesting connections from the pool may block
-     *         until other workers return their connections. This field shows how many
-     *         milliseconds workers have blocked for connections to be released. If this number
-     *         keeps increasing, you may want to use MongoPool::setSize to add more connections
-     *         to your pool
