This reverts commit e1b80468 and 5057e18a.

Hex is longer then normal text and can faster lead to tag longer then 255
characters, which is deadly.

Damaging sla and instance xml is not possible anymore.

As getFullcomputerInformation is used by slap library, there will be always
something transmitted.

Stopped is also finished state, so do not take it as "something in progress".

Do it as well for the reporting loop.

We don't care about creating (and possibly fetching informations to server) Partition object if we don't do anythign with it.

Data can be really complex string, which can be bad for tag.

getFullComputerInformation is being used, so there will be no empty response.

Instance Setup delivery is immediately delivered.

getSoftwareReleaseList is updated by getFullComputerInformation call, which
returns everything, even destroyed (and theoretically forgotten) software
releases.

This will allow portal_deliveries/vifib_sale_invoice_builder to put movements
on prepared invoice.

There will be such delivery, as side effect of automatic bang.

One for "State changed from draft to start_requested"  and second one for
"Parameter changed".

There is more work to do then confirming invoice.

This follows alarm configuration, which just moves empty (stub) invoices for
next month.

This allow to work in case of Slave Instances.
