[Tarantool-patches] [PATCH v1 0/2] tarantoolctl: add signal in stop/restart options

[Alexander V. Tikhonov]

Found that some of the instances could not be killed with SIGTERM signal
and it really needed SIGKILL signal to be sure that the instance would
be terminated. Otherwise some tests may fail, like:

  No output during 120 seconds. Will abort after 120 seconds without output. List of workers not reporting the status:
  - 001_engine [engine/json.test.lua, memtx] at var/001_engine/json.result:598
  Test hung! Result content mismatch:

Test run uses 'tarantoolctl' tool for commands in format "restart server
default", and 'tarantoolctl' had only single way to kill it using
SIGTERM signal. To implement ability to use it with SIGKILL was added
additional non-mandatory option to stop and restart 'tarantoolctl'
commands, like:

  tarantoolctl stop <instance> [--signal=SIGKILL]
  tarantoolctl restart <instance> [--signal=SIGKILL]

This options didn't change the backward compatibility of 'tarantoolctl'
tool, but gave the tests ability to stop and restart instances in the
following way:

  test_run:cmd("stop server default with signal=KILL")
  test_run:cmd("restart server default with signal=KILL")

It helped to fix the issue with hanging instances in the needed tests.

After test-run changed for the new 'tarantoolctl' format for 'restart'
and 'stop' commands some tests had to be updated due to checked it.

Closes #5510
