#430: BibEdit: make it work in load-balanced architecture

----------------------+-----------------------------------------------------
When running in a multi-node environment, BibEdit has troubles since
it caches files in per-node `/opt/invenio/var/tmp` directory. This
can lead to errors like:
{{{
A server error has occured. You may have lost your changes to this record.
Error code: 106 (missing cache file)
}}}
because the cache file may be created on one worker machine and cannot
be accessed from another worker machine.
The solution would be (1) to redirect `/record/edit` URLs always to the
same worker by the load-balancer; (2) to use `tmp-shared` space on AFS
that is common to all worker nodes; (3) to use DB for storing BibEdit
cache files.
The former looks like a workaround, the middle may be useful to many
modules, only the latter is BibEdit-specific. However, storing
cache files in DB may be good to do regardless of the `tmp-shared`.
