Added env to exclude containers from cpu/memory docker graphs

It maybe desirable to not generate stats for ephemeral containers.
This commit adds an env variable EXCLUDE_CONTAINER_NAME which is a regex, if it matches
then the container is excluded from the cpu and memory graphs.

You can use the EXCLUDE_CONTAINER_NAME environment variable to specify a regular expression

which if matched will exclude the matching containers from the memory and cpu graphs.

For example


  		




  
  45
  
    

  		




  
  46
  
    
env.EXCLUDE_CONTAINER_NAME runner


  		




  
  47

Would exclude all containers with the word "runner" in the name.
