The maintenance alarm handling daemon (mtcalarmd) should not
drop alarm requests simply because FM process is not running.
Insteads it should retry for it and other FM error cases that
will likely succeed in time if they are retried.
Some error cases however do need to be dropped such as those
that are unlikely to succeed with retries.
Reviewed FM return codes with FM designer which lead to a list
of errors that should drop and others that should retry.
This update implements that handling with a posting and
servicing of a first-in / first-out alarm queue.
Typical retry case is the NOCONNECT error code which occurs
when FM is not running.
Alarm ordering and first try timestamp is maintained.
Retries and logs are throttled to avoid flooding.
Test Plan:
PASS: Verify success path alarm handling End-to-End.
PASS: Verify retry handling while FM is not running.
PASS: Verify handling of all FM error codes (fit tool).
PASS: Verify alarm handling under stress (inject-alarm script) soak.
PASS: verify no memory leak over stress soak.
PASS: Verify logging (success, retry, failure)
PASS: Verify alarm posted date is maintained over retry success.

This decouples the build and packaging of guest-server, guest-agent from
mtce, by splitting guest component into stx-nfv repo.
This leaves existing C++ code, scripts, and resource files untouched,
so there is no functional change. Code refactoring is beyond the scope
of this update.
Makefiles were modified to include devel headers directories
/usr/include/mtce-common and /usr/include/mtce-daemon.
This ensures there is no contamination with other system headers.
The cgts-mtce-common package is renamed and split into:
- repo stx-metal: mtce-common, mtce-common-dev
- repo stx-metal: mtce
- repo stx-nfv: mtce-guest
- repo stx-ha: updates package dependencies to mtce-pmon for
service-mgmt, sm, and sm-api
mtce-common:
- contains common and daemon shared source utility code
mtce-common-dev:
- based on mtce-common, contains devel package required to build
mtce-guest and mtce
- contains common library archives and headers
mtce:
- contains components: alarm, fsmon, fsync, heartbeat, hostw, hwmon,
maintenance, mtclog, pmon, public, rmon
mtce-guest:
- contains guest component guest-server, guest-agent
