This update introduces support for application dependencies on
specified software patches. This allows sysinv to query patch states
and to report application dependencies, to block removal of required
patches.
APIs introduced:
is_applied: Provide a list of patch IDs. Returns True if ALL patches
are in Applied (fully applied/installed) state, False if any are
not.
report_app_dependencies: Provide an app name-version string and list
of patches.
* Apps are dropped by reporting app name with no patch list / empty
list.
* Triggers sync with patch-controller neighbour (ie. standby
controller)
query_app_dependencies: Query for dict of app => patch list, for all
reported apps.
On patch removal, the patch-controller checks to see if the patch
being removed is required by any applications. Reject the removal,
if so.
* Provide backdoor --skipappcheck option to skip this dependency
check.
