amfd: Add support for cloud resilience at director [#1620] V2 Outlined
changes: . node_up_msg event handling has changed so that amfd can
collect
the sync information sent from amfnd . Node Sync timer is introduced as
a
window of amfnd sync from headless . Failover may happens during
headless,
adjust_delayed_failover() to balance the assignment in term of
active/standby availability . SI dependencies also can change due to
assignment removal during headless adjust_delayed_sidep() to update the
si
dependencies

recovery is limited during headless, only componentRestart and
suRestart is
supported . SC absence timer is introduced, node will reboot if timeout

amfd: Add saAmfUnassignedAlarmStatus attribute to memorize the
alarm_sent
status [#1620]
If the SI Unassigned Alarm is raised before headless by locking SU for
instance, then after cluster recovers from headless and unlocking the
SU,
this alarm is not cleared. As the application can reside in PL nodes and
it's right to expect the previous raised alarm should be cleared once
the SI
gets back assignments. The patch adds new attribute
saAmfUnassignedAlarmStatus attribute to SaAmfSI class to memorize the
variable alarm_sent for headless.

-----------------
To test this feature, needs patches of #1625, #1646 as minimal
and preferly to have patches of #1179, #1180 and #1621
Test: bring down both SCs, and start SCs back
Testing, Expected Results:
--------------------------
PL nodes do not reboot, and cluster comes back healthy after
SCs come back from headless

Reviewer Checklist:
-------------------
[Submitters: make sure that your review doesn't trigger any checkmarks!]
Your checkin has not passed review because (see checked entries):
___ Your RR template is generally incomplete; it has too many blank entries
that need proper data filled in.
___ You have failed to nominate the proper persons for review and push.
___ Your patches do not have proper short+long header
___ You have grammar/spelling in your header that is unacceptable.
___ You have exceeded a sensible line length in your headers/comments/text.
___ You have failed to put in a proper Trac Ticket # into your commits.
___ You have incorrectly put/left internal data in your comments/files
(i.e. internal bug tracking tool IDs, product names etc)
___ You have not given any evidence of testing beyond basic build tests.
Demonstrate some level of runtime or other sanity testing.
___ You have ^M present in some of your files. These have to be removed.
___ You have needlessly changed whitespace or added whitespace crimes
like trailing spaces, or spaces before tabs.
___ You have mixed real technical changes with whitespace and other
cosmetic code cleanup changes. These have to be separate commits.
___ You need to refactor your submission into logical chunks; there is
too much content into a single commit.
___ You have extraneous garbage in your review (merge commits etc)
___ You have giant attachments which should never have been sent;
Instead you should place your content in a public tree to be pulled.
___ You have too many commits attached to an e-mail; resend as threaded
commits, or place in a public tree for a pull.
___ You have resent this content multiple times without a clear indication
of what has changed between each re-send.
___ You have failed to adequately and individually address all of the
comments and change requests that were proposed in the initial review.
___ You have a misconfigured ~/.hgrc file (i.e. username, email etc)
___ Your computer have a badly configured date and time; confusing the

___ Your changes affect IPC mechanism, and you don't present any results
for in-service upgradability test.
___ Your changes affect user manual and documentation, your patch series
do not contain the patch that updates the Doxygen manual.
