New feature: "Network Connection Pool" now is stable

Network Connection Pool
Each client, by default, uses only one network connection to talk with the server. Multiple threads on the same client share the same network connection pool.
When you've multiple threads could be a bottleneck since a lot of time is spent on waiting for a free network connection. This is the reason why is much important to configure the network connection pool.
The configurations is very simple, just 2 parameters:
- minPool, is the initial size of the connection pool. The default value is configured as global parameters "client.channel.minPool" (see parameters)
- maxPool, is the maximum size the connection pool can reach. The default value is configured as global parameters "client.channel.maxPool" (see parameters)
At first connection the minPool is used to pre-create network connections against the server. When a client thread is asking for a connection and all the pool is busy, then it tries to create a new connection until maxPool is reached.
If all the pool connections are busy, then the client thread will wait for the first free connection.
Example of configuration by using database properties:
database = new ODatabaseDocumentTx("remote:localhost/demo");
database.setProperty("minPool", 2);
database.setProperty("maxPool", 5);
database.open("admin", "admin");
