Replace sleep code

[Philip May]

IMO this code:

prometheus-smartctl/smartprom.py

Lines 176 to 184 in 3fbd7bb

 collect() 
  
 start_time = time.time() 
 while True: 
     elapsed_time = time.time() - start_time 
     if elapsed_time > 20.0: 
         start_time = time.time() 
         collect() 
     time.sleep(0.1) 

can be replaced by just this:

    while True:
        collect()
        time.sleep(20)

What do you think?
