Then using caucase implies monitor, and it's not required to do so in the
softwares using monitor.

Adding monitor stack allows to use the monitor, then passing the profile and
extending it allows to correctly deploy.

Notes

stack/erp5

 * The service-auto-approve-amount to default is set to 1, in order that the
   only needed service is automatically approved.  As caucase is accessed
   internally (on local IPv4) only partitions on the same server will access
   caucase.

The caucase parameter 'auto-sign-csr' used to say if the first csr should be signed
was changed to 'auto-sign-csr-amount' to let specify how many csr can be signed without
human intervention.
This parameter will be set to 2 in erp5 software release, so that caucase http server and
apache server cas request thier certificate automatically.

certificate-authority software release and stack was renamed to caucase
