Bad relative path handling between command line client and daemon

If the command line client is provided a manifest file by relative path e.g. ./doc/manifest, the path is provided as is to the daemon, which is probably not in the current working directory. This can trigger File not found errors on the daemon side.

2 possible solutions:

• resolve the absolute path in the cli tool, and check that the file exists, before giving it to the daemon
• read the manifest in the cli tool, and provide the manifest info to the daemon as a command argument.

The second solution is probably cleaner for the long term.
