The keepalived does support script call handling on start and stop.
All scripts located under '/etc/hotplug.d/keepalived' gets now called
with the env ACTION set to startup or shutdown. The script that want to
get called on this keepalived events could evalutate this env to run on
startup or shutdown.

add new package keepalived-sync to synchronize files and data
between master and backup node. The master node uses SSH over rsync
to send and the backup node will use inotifywatch to watch received files.
The master node can track rsync.sh script to send configuration file on
a backup node based on the vrrp_script configuration of the same script.
The backup node will have a keepalived-inotify service, which would watch
for newly received files and it would call hotplug event. Each service
can keep its respective script under the keepalived hotplug directory and
executes commands to stop, start service or update any config in real-time.
Whenever a switchover will happen, the backup node would have the latest
config and data files from the master node.
Hotplug events can be used to apply config when files are received.

Openwrt is a single user system. So keepalived is runnig as root.
If we add the config options `script_user root` and
`enabled_script_security' the following warnings are gone.

Remove unsupported "notify" script during uci config generation.
This change will remove keepalived warnings on startup.

Append use_vmac with no_val_ so that the uci generation will treat this
as an boolean option. If the option is set then a interface with
vrrp.{virtual_router_id} is added to the system.

If ip is referenced in the instance section it is not necessary to add a
device option on every "ip_address". In most sitution it es enough to
add only an ip. Allow empty device option will solve this issue.

During keepalived config generation for the vrrp_instance and vrrp_sync_group
the notify_* sections are automatic added to the runtime keepalived.conf.
This could be used for service which want to react on keepalived notifications.

In a vrrp_instance the track_interface could not be referenced similar
to a track_script. The uci track_interface section must be always set
into every vrrp_instance.
During config generation use the already prepared function
"print_track_elem_indent" to write the track_interface section into every
vrrp_instance which references this.

If you add a notify_* script which is not only a path to a script or
to a bin file, it is necessary to quote to whole string. If you do not
quote this the config will not get accepted by keepalived and so will
not start. This will fix this issue.

keepalived seems to be rather particular about which config parameters
come before others.
When defining a virtual IP address, keepalived will check to see if the
vrrp instance is associated with a valid interface. Previously, the
interface parameter was declared after the virtual IP address which
caused an error when keepalived tried to run this check. Keepalived
tries to fall back to checking if 'eth0' exists.
The fix is to re-order the config stanzas so that the interface
parameter comes before the virtual IP address definitions.

Also fix ordering of config stanzas
We were parsing the track_script and track_interface definitions to
include the weight param when configuring a vrrp_instance. This is not
correct, as the weight param inside a vrrp instance is used to augment
the one defined in the script.
We were also not taking into account vrrp_script stanzas
This commit skips the parsing and simply lists the name of the
track/vrrp object
