Decouple Guest-server/agent from stx-metal

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

This maintenance common guest service was introduced in cgts release 2 in order to
provide a means of guest heartbeat orchistration under VIM (system management) control.
This module includes header files exported to the sysroot by the original cgts
release 1 heartbeat service for messaging structure definition.
That original module builds a common heartbeat daemon capable of running on the
controller, compute and within the vm. The controller version did nothing except
for respond to heartbeats from the compute version. The compute instance was the
brains of the heartbeat service reponsible for starting heartbeat to the VMs and
interfacing with Nova to take actions.
The introduction of this module changes a large part of that.
Here is a summary of the changes
1. Packaging and Initialization:
The source code for the original cgts release 1 heartbeat daemon remains
unchanged but the packaging of the heartbeat daemon and heartbeat_init
script are modified
a. image.inc and filter_out packaging files are modified to exclude the
heartbeat daemon from being packaged on the controller.
b. because the heartbeat daemon is still packaged on the compute
heartbeat_init script is modified to prevent the heartbeat
daemon from being spawned on the compute host.
Note: the heartbeat daemon continues to be packaged and spawned in the guest
as it did in release 1 - no change there.
2. Compute Function: Heartbeats the guest and reports failures.
Package: cgts-mtce-common-guestServer-1.0-r54.0.x86_64.rpm
Binary: /usr/local/bin/guestServer
Init: /etc/init.d/guestServer
Managed: /etc/pmon.d/guestServer.pmon
3. Controller Function: Guest heartbeat control and event proxy
Package: cgts-mtce-common-guestAgent-x.x-rxx.x86_64.rpm
Binary: /usr/local/bin/guestAgent
Init: /usr/lib/ocf/resource.d/platform/guestAgent
Managed: by SM
The heartbeat daemon that did run on the controller is replaced by a new
guestAgent daemon performing the following functions
a. HTTP Command Receiver : to which the VIM sends instance control commands.
b. HTTP Event Transmitter: to which the daemon can send instance failure
events and state query commands to the VIM.
c. State query audit to the
Behavioral Executive Summary:
The guestServer daemon (on the compute) listens for (using inotify) 'uuid'
UNIX named heartbeat communication channels that nova:libvirt creates and
opens in /var/lib/libvirt/qemu whenever an instance is created. Example:
/var/lib/libvirt/qemu/cgcs.heartbeat.02e172a9-aeae-4cef-a6bc-7eb9de7825d6.sock
The guestServer connects (and auto reconnects) to these channels when they are
created or modified and disconnects from them when deleted.
Once connected, the guestServer listens for TCP messages over that UNIX named
socket.
If a guest supports heartbeating then it will run the heartbeat_init script
during its initialization process. Once the heartbeat daemon is running it
will periodically send init request messages to the libvirt pipe that,
on the host side, the guestServer is listening for.
on receipt of an init message, the guestServer will extract name, timeout
and corrective action info from it and then send back an 'init_ack' followed
by a continuous heartbeat cycle consisting of sending a 'challenge' request
messages and expecting a correct computational responses within a guest specified
heartbeat window. Failure to comply will result in a corrective action that was
specified in the init message from the guest.
The VIM is responsible for enabling and disabling heartbeat fault reporting as
well as taking the guest specified corrective action in he event of a heartbeat
failure.
