Move the ngcp object variable into NGCP::Template::Object, and make
NGCP::Template just a customized variant of Template that we can use
instead.
This way we hide all the internal details of how to set up the
environment we need to process NGCP templates.

The perl Template::Toolkit is very rich, but its "function" support is a
bit poor. The ways to do it are either via MACRO directives, or by
simulating them with one function per file and then using PROCESS on
these. The problem is that this is very clunky, does not support
nesting, as we'd need different "argument" names for each "function",
and it's quite cumbersome to use, need to assign aguments passed
beforehand, and then assign back a designated return value from another
variable. This is also one of the reasons some of the functions are not
encapsulated, and have been inlined in various loops, because it was not
possible to cleanly PROCESS them from those call sites.
Instead we should use its native support for perl objects and perl
subroutines, which exposes these as proper methods of a designated
variable, and have none of the above mentioned problems. So we'll switch
from constructs such as:
argv.arg-a = variable;
argv.arg-b = 'value';
PROCESS 'path-to-library-dir/function'
result = out
into:
result = ngcp.function(variable, 'value');
In addition this might actually be faster, as it does not require
processing additional files, and it's all just native perl code.
This will be exposed within the NGCP templates as the ngcp object, and
new member functions will start replacing our old and clunky native
Template PROCESS-style library.

If the file /etc/hosts gets handled by templates, as ongoing changes
attempt to do, there's a problem because /etc/hosts gets truncated to
create a new file when it's needed to generate itself, to resolve the
"localhost" string as hostname, so the generation fails and /etc/hosts
gets empty at that point, affecting the system until restored.
The simplest way to break that cycle is to switch to Unix sockets.

The latter does not support YAML 1.1, nor many parts of the
specification. Use the more compliant implementation, in addition to try
to converge to a single one, so that we do not get serialization delta
surprises.

This module is more compliant and it is faster than the pure perl
implementation. The latter is also deprecated in favor of the former
(see man YAML for more details).

The default Hash::Merge->merge() behaviour is LEFT_PRECEDENT:
http://search.cpan.org/~rehsack/Hash-Merge-0.200/lib/Hash/Merge.pm
Which means:
> The values buried in the left hash will never be lost;
> any values that can be added from the right hash will be attempted.
So, the values from HOST_CONFIG never overwrites default NGCPCTL_CONFIG:
> NGCPCTL_CONFIG="${NGCPCTL_MAIN}/config.yml"
> HOST_CONFIG="${NGCPCTL_MAIN}/config.$(hostname).yml"
We need to use RIGHT_PRECEDENT order to be in sync with 'scripts/build':
> ${NGCPCTL_CONFIG:-} ${HOST_CONFIG:-} ${LOCAL_CONFIG:-} ${NETWORK_CONFIG:-} ${EXTRA_CONFIG_FILES:-} ${CONSTANTS_CONFIG:-}

- added quiet option to disable loading output at tt2-daemon
- detect arrays and output values joined by space
Change-Id: I0b7694a366a284ca2b24ea2df55cb285b598e66d
We will use first free port instead which will be stored into
/var/run/ngcpcfg.port file while tt2-daemon is up and running.
