Add support for of1.3.

Add support for of1.3.

- Modified controller.spec to:
  - support the of1.3 option
  - support the three different run.sh scripts for the different distributions
- Added run.dist.sh script to wrap all the run.sh scripts. This file is called by the systemd and sys init scripts.
- Added patch file to modify the run.sh calls to run.internal.sh. The files assume run.internal.sh is in the same working directory as the wrapper run.sh which is not the case with systemd or sysv installs.
- Added distribution options to opendaylight-controller sysconfig. File is used to select the distribution to start.
