cooker: simplify tag and add caller metadata
Group the metadata information:
- simplify the json by removing the 'tag' and only using 'get' and 'set'
keys
- get uid and gid at runtime for the target ('caller'). This can be useful when
the the UID and GID of the target are only known at runtime and they
need to be used for setting the permissions of files
- updated example demo/mknod.hjson
