Remove trailing spaces. Get rid of an unused method.

1. sleep(0.1) -> sleep(0.01)
2. _server -> serv, _replica -> _repl.

2. Refactor find_tests code
3. Rewrite and Add comment for chdir(base) (test_run.py:145)
4. Rewrite .gitignore file for new name of unit tests

*Add uncommited file (lib/test-suite.py)

*Delete obsolete code

*Refactor of TestSuite and Test code

In the first place Tarantool has only one kind of test - functional testing.
But, when system began to grow, and each component (inside it) is needed to be tested thoroughly.

* 	Added support of UnitTest without creating of *.test file, that contains "run_test("*")"
	(Added UnitTest(Test) in the unittest_server.py, FuncTest(Test) in the tarantool_server.py.
	Now, when we search for tests we tell server to search them, and when we want to execute all
	tests TestSuite runs `execute` method of specific Test subclass)

* 	Fix of bug, that throwing OSError exception, when running by "python test-run.py",
	instead of "./test-run.py"

This patch needs for correct work of out-of-source builds
from tarbals without .git repository within.

autogenerate version file which can be used
in case when there is no .git repository available within sources and
it is crucial to properly display current version.

The Linux fix was broken by portability changes when
porting to FreeBSD.
When checking for a special case of getaddrinfo() failure,
check for both, EAI_BADFLAGS and EAI_ADDRFAMILY.
