Currently, for SNMP requests, we have new walk[oid] item which can work asynchronously and improves SNMP performance greatly. Although walk[oid] can be used for single OID metrics, it is not meant for that, as an extra preprocessing step needs to be applied to extract the value from result and also performance-wise - it first tries to receive multiple values first, even if single OID is requested.

So, a new asynchronous get[oid] method would be useful for querying single OIDs, that directly outputs the value without additional data about OID and value type.

It would also be nice if this item would have a possibility of converting its value to different formats, just like SNMP walk value preprocessing step can do now (Unchanged, UTF-8 from Hex-STRING, MAC from Hex-STRING, Integer from BITS)
