test: add integration tests

test-run supports three types of tests:

- tarantool - Test-Suite for Functional Testing
- app - Another functional Test-Suite
- unittest - Unit-Testing Test Suite

Patch adds tests for two of supported test types:

- test-app for type 'app'
- test-tarantool for type 'tarantool'

How-to run:

$ make test_integration

- test-tarantool/panic_on_broken_lsn.test.lua [1]
