My fault - got used to editing such files in default vim. Fixed and updated
vim settings to indent with spaces.

Strange error - shell expansion is not working. Anyway, replaced with more
universal variant.

Extracted corresponding sections into separate files.

AFAIK, PDS is actively pushing forward and has to be enabled by default so
that Ignite users start working with PDS from the very beginning.

Unfortunately, I did not find any other way to open ports and multicast,
except applying direct iptables rules though firewall-cmd -- so there can be
no separate service firewall rules file (as can be found here:
/usr/lib/firewalld/services). Applied rules from package go straight to
/etc/firewalld/direct.xml. If we agree not to put Multicast-enabled by
default configuration file and will stick to IP Discovery, I'll try to
revise firewall configuration and create separate service firewall rules
file (but, I guess, much later).

The problem exists mainly because of sqlline.sh|ignitevisorcmd.sh
unaware-of-package design and I see the following 3-step way to overcome
this limitation.
At first we hide this executables file in examples (As Iliya proposed).
Secondly, I can design a patch, which can be applied during package build,
so that those executables work normally form the package installation.
And lastly, redesign them to be universal and compatible with all delivery

Moved libs to /usr/lib/apache-ignite and mapped to
/usr/share/apache-ignite/libs (for backward compatibility). I guess later we
have to think out of a solution to load libs directly from /usr/lib (along
with configurations / logs / work / etc.)

It's not an ordinary task to create "100% honest" package, so I guess we
definitely won't make to 2.4 release. So I purpose include in the nearest
release our package built from binary archive and do not supply sources
package (as it is currently done in apache.org/dist for cassandra / hadoop
or alike). And later design package build procedure, which includes getting
sources from sources distribution, or even from Apache Ignite Git repository

Release procedure on TC is already has some task for project version update,
so I guess it is not so difficult to update it accordingly (as it is
currently done for C++ / .Net internal versions).

So the only question to discuss (according Iliya's review) is whether to
supply package with default-config.xml that has Multicast Discovery turned
on or not?

Also I'll appreciate any other comments concerning current package design.
