Switch Abstraction POC.

Switch Abstraction POC.

- switch user made dynamic and defaults to ${MININET_USER}
- added ssh_key functionality for switches that use ssh for mgmt_protocol
- moved switch classes to a subdir in libraries for tidiness
- made Ovs default and SWITCH_IP == ${MININET} so that no changes
  need to be made to jenkins job

using @property for dynamic switch class attribute strings

moved some attributes to properties so that the values of the
properties could change dynamically as other class attributes
are changed (e.g. when you get a flow object you need to update
the controller_ip, and because of that a lot of the strings
(for configs, etc) need to be updated in real time)

moved generic keywords to new SwitchUtils library

also:
-  ${SWITCH} and ${CONTROLLER_IP} need to be passed as cmdLine
   args regexp will now match verifications, so long strings
   can be condensed in object definition (if desired)
