    Just invalidate the certificate login

    This drops certificate revocation, it only requires to invalidate the Certificate Login to make login invalid.

   revoke occur directly on the Certificate Login

   Other users wont have permission to cancel valid Certificate Logins, only Compute Node owners.

  Now we dont rely on the document reference anymore.
  Invoke generateCertificate on tests else the user isnt valid.
  Note:  Login name returns the Certificate Login reference, to keep
    backward compatibility with the API (and current usage) it user
    the actual user reference, so it is easier to identify which document
    set the access status.

   This issues SSL Certificates and use Certificate Login, rather them require to revoke it.

   Display only the Software Releases and if they can allocate or not, since display individual computers are not exactly good.
   Filter compute nodes by allocation scope (not closed forever)

   Include few fields and adjust the listbox columns to be user friendly (Display title rather them id).

ssh-keysign is not readable by everyone so we cannot do "ldd" on it:

$ ls -al /opt/slapgrid/shared/openssh/f79ee5e4e4573183783541f2ad9133e8/libexec/
total 1332

we can have a case where written slapos.cfg has "partition_amount = 10"
(leftover from previous execution) and we call format(0), in this case,
we really want slapos.cfg function to be rewritten.
