[Xen-devel] [PATCH OSSTEST v3 1/8] HostDB: introduce set_property

[Roger Pau Monne <roger.pau@xxxxxxxxxx>]

And provide a helper in TestSupport to use it. This allows osstest to
set host properties from test script themselves (instead of using
the mg-hosts clu).

Note that the setting of host properties is limited to flights with
intended blessing real, and it will fail for any other blessing.

Signed-off-by: Roger Pau Monné <roger.pau@xxxxxxxxxx>
---
Changes since v2:
 - Die if attempting to modify a host prop with intended blessing !=
   real.
