nxos_ssh get_environment fails to parse temperature info

[raa-1]

Description of Issue/Question

My Nexus 3000 switch gives this as an output of show environment temperature command:

swi-01# show environment temperature 
Temperature:
-------------------------------------------------------------------------
Module  Sensor             MajorThresh   MinorThres   CurTemp     Status 
                           (Celsius)     (Celsius)   (Celsius)           
-------------------------------------------------------------------------
1        Back-Right (D0)   70            44            27         Ok             
1        Back-Left  (D1)   70            42            28         Ok             
1        Front-Right(D2)   70            47            29         Ok             
1        Front-Left (D3)   70            49            35         Ok    

This code splits the line, but it doesn't expect there are whitespaces in the Sensor value, thus unpacking fails.

I suggest using something like this:

module, sensor, is_critical, is_alert, temp, _ = re.match(r'(\d+)\s+(.*?)\s+(\d+)\s+(\d+)\s+(\d+)\s+(\w+)\s+$', line).groups()
