Set the minimum number of connections to keep available at all times. When the pool is created,
it will create this many connections. If <code>0</code> then connections will not be made until
an actual operation is done that requires client-to-server communication.

@param minConnections the initial number of connections this pool will create.
@return a reference to <code>this</code>
@throws IllegalArgumentException if <code>minConnections</code> is less than <code>0</code>.
