docker-plugin 0.8 : jenkins 1.609 : issues and fixes

[Hanasaki Jiji]

Looking at using docker-plugin vs arquillian cube.  For the current needs, prefer the plugin since it puts control of the docker vm's outside of developer and the use of docker for the slave is hidden. 

Few issues I ran into:

1. docker slaves are launched but jenkins cannot ssh to them (same issue as someone else posted).
   
2. Docker slave container is never torn down when #1 happens
3. Slave names contain an '@' which Jenkins flags as a dangerous character.
4. How to pass options like "-m1G  -rm"

Would it make sense to try to leverage the arquillian cube libraries as a client controller for this plugin and turn the plugin into more of a facade / adapter?
