Add namedprocess_namegroup_tcp_socket_count metrics
1b1cc01 
Some times, we need to know how many TCP socket are used by a process or
a group of process.
Adding this metrics allows to know precisely the number of socket
created and their states.

Les process semblent être dupliqués, rendant la métrique fausse

EDIT: Au final non, ce sont bien des process différents
EDIT2: C'est pas bon

C'est pas bon en fait ; /proc/X/net/tcp retourne la même valeur quel que soit le PID (X)
