[manager] The API for snmp requests has been changed to + allow the caller to override some configuration.

[manager] The old API functions (for get and set - requests) are now officially deprecated. + requests: + snmpm:g/3,4,5,6,7, snmpm:ag/3,4,5,6,7, + snmpm:gn/3,4,5,6,7, snmpm:agn/3,4,5,6,7, + snmpm:s/3,4,5,6,7, snmpm:s/3,4,5,6,7, + snmpm:gb/5,6,7,8,9 and snmpm:agb/5,6,7,8,9) + are now officially deprecated. They will be removed as of R16B.
