A few minor fixes, related to issue #3:
- Fixed module and class name references to point to "zk_watcher" rather than "zk"
- Fixed python dependency to be on package rather than class
- Added metadata.json file, that specifies dependency on puppetlabs/concat (which was required)
- Added a .project file for Geppetto
- zk_watcher no longer accepts the --foreground parameter
Remove \n and replace back double quotes with single quotes
