Currently, we are using atomic_t to track the number of connections. On 64-bit setups with large memory there is a risk this counter to overflow. Also, setups with many containers may need to tune the limit for connections. Add sysctl control to limit the number of connections to 1,073,741,824 (64-bit) and 16,777,216 (32-bit). Depending on the admin's privilege, the value is used to change a soft or hard limit allowing unprivileged admins to change the soft limit in range determined by privileged admins.
