Structure and file for the SNMP client
Change almost all the plugins to host the SNMP input plugins
Factorisation of the SNMP set
SNMP input: Uptime and CPU
SNMP input: Mem and MemSwap
First try for SNMP net interface: had to be optimised with bulk requests
SNMP client: Network interface is OK but high CPU consumption
SNMP grab OK for file system
Difficult to get CPU core number via SNMP. Bypass
SNMP client: all plugin OK except processing list. To hight CPU consump with the standard loop
Correct encoding/deconfing problem with special caracter
Change connection message. Add SNMP client
Add args visibility to the plugins to handle with the SNMP server properties (address, community...)
Add note for future optimisation
Manage SNMP if there is no standard stats
SNMP client: compute ifNumber if it is not available
Add configuratino varfor SNMP community and port number
Allow SNMP v3: To be verified/check
Allow SNMP v3: To be verified/check
Check if mem stat is available before converted it to KB
