   Automatically destroy and invalidate duplicated software installations, in same state. This is helpful if concurrent requests had created multiple supplies.

  This prevents +2 supplies on the request creates more them one software installation with same url on a compute  node.

  The requestSoftwareRelease don't have proper raise in case 2 supplies are done on the same transaction.

   hateoas url is the website but it requires ssl authentication (like portal_slap), while the slapos_master_web_url is the website the user is accessing (no ssl authentication required).

  It seems that was broken for quite long.

   Update typo on field title

   Remove field that uses internal packing list for display location, since this API was completely dropped.

   If we want to reintroduce it will done differently.

  Configure payable required extra effort, and we should keep default simple.

  So drop entries in tests or upgrades since it is not considered anyway.

  Since the Base_getStatusMonitorUrl  uses try/except, it didn't detect that the file was missing.

  Copied from slapos_jio (which was removed).

   Only Computer enable/disable the monitoring now.

   Monitor scope is per computer bases only, so remove the field since it is not applicable anymore.

  This test seems never ever implemented since the begin of the project

   This implements checkValidity properly.
