Added csv-stats to output pre-gnmi and gnmi telemetry data in csv format.
Moved few print statements to stream log file

Example:
./jtimon-linux-amd64 --config test.json --no-per-packet-goroutines --stats-handler

To get the csv file, need to set to true within internal-jtimon configuration. csv output file path can also be specified in internal-jtimon but its not mandatory.

Sample Configuration:

{
    "host": "10.54.130.1",
    "port": 32767,
    "user": "root",
    "cid": "external2",
    "password": "Embe1mpls",
    "vendor": {
        "gnmi": {
          "encoding": "protobuf"
        }
    },    
    "internal-jtimon" : {
        "data-log-file": "/homes/regress/test/gnmidatata.log",
	"csv-log-file": "/homes/regress/test/test.csv"
    },
    "eos": true,
    "vendor": {
        "gnmi": {
          "encoding": "protobuf"
        }
    },
    "paths": [{
        "path": "/system/processes/process/state/",
        "freq": 10000
    },
    {
	"path": "/components/",
        "freq": 10000,
	"pre-gnmi": true
    },
    {
        "path": "/system/alarms/",
        "freq": 10000
    }],
    "log" : {
        "file": "/tmp/test-jtimon.log",
        "verbose": false
    }
}
