// TransportClientSocketPool establishes network connections through using
// ConnectJobs, and maintains a list of idle persistent sockets available for
// reuse. It restricts the number of sockets open at a time, both globally, and
// for each unique GroupId, which roughly corresponds to origin and privacy mode
// setting. TransportClientSocketPool is designed to work with HTTP reuse
// semantics, handling each request serially, before reusable sockets are
// returned to the socket pool.
//
// In order to manage connection limits on a per-Proxy basis, separate
// TransportClientSocketPools are created for each proxy, and another for
// connections that have no proxy.
// TransportClientSocketPool is an internal class that implements almost all
// the functionality from ClientSocketPool.
