No sql option

[will-moore]

NB: this is on top of #8.

In cases where we've run a lengthy omero mkngff sql... command on e.g. a test server (e.g. idr-testing) and we wish to reuse the generated sql files on a different clean server (starting from the same state - same Fileset IDs, paths/to/fileset.zarr etc, we still need to create the symlinks on the new server, without walking the fileset.zarr which can take a long time.

This PR adds a symlink command to ONLY create symlinks.

E.g:

$ omero mkngff symlink /OMERO/ManagedRepository 1161 /path/to/fileset.zarr

Viewing image from that last Fileset above (Plate P127): http://localhost:1080/webclient/?show=image-693716 gives:

serverExceptionClass = ome.conditions.ResourceError
    message = Error instantiating pixel buffer: /data/OMERO/ManagedRepository/demo_2/2015-10/01/08-02-58.826_mkngff/fcc7c91a-f0e6-43f4-93a6-220e9224eda5.zarr/.zattrs

But the data (symlink) is correct:

(base) [wmoore@pilot-idr0125-omeroreadwrite ~]$ ls -alh /data/OMERO/ManagedRepository/demo_2/2015-10/01/08-02-58.826_mkngff/fcc7c91a-f0e6-43f4-93a6-220e9224eda5.zarr/

TODO: test whether there's an issue with creating symlinks and generating sql separately... (do both, independently on the same server), then run sql and...?
